In this experiment the masses of pieces of magnesium ribbon will be determined indirectly. Magnesium reacts with hydrochloric acid to produce aqueous magnesium chloride and hydrogen gas. From the volume of hydrogen gas collected, the mass of magnesium can be calculated using Dalton's Law of Partial Pressures and the Ideal Gas Law. Mg (s) + 2 HCl (aq) → MgCl2 (aq) + H2 (g)

A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other that form an insoluble compound, they suddenly fall out of solution in what's called a precipitation reaction. In this episode of Crash Course Chemistry, we learn about precipitation, precipitates, anions, cations, and how to describe and discuss ionic reactions.

Determination of molar mass by Victor Meyer
 
04:20
Faculty of Chemical Engineering and Technology,Zagreb People involved in this project: Magdalena Pavljak, KIM Elvira Pek, KIM Petra Travančić,KI Elena Vlačić, KIM Boris Vučić, KIM The purpose of the experiment: Determine the molecular weight of an unknown organic compound. Instruments needed for the experiment: • internal pot • external pot with the ester • measuring burette • leveling pot • metal cylinder • caps • 2 ampoules Chemicals: • propylene glycol ester • organic solution Experiment description: Metal cylinder, which serves as thermal isolation, should be put on a tripod with the asbestos mesh. Attach the external pot with the ester within the cylinder. Dry out the internal pot and place it inside the external pot, and secure it in place with a cork so that the internal pot is placed above the ester level in the external pot. Internal pot must then be connected with the leveling pot. Once the apparatus is prepared, it can be heated. Sample preparation: Trim the ampoules according to the apparatus, and then weigh them on an analytic scale. First ampoule should be heated and then immersed in the sample vial. When ampoule is filled to half, fuse its top, and weigh it again. When apparatus is heated enough, place the magnet through the opening, put a plug in it and attach an electromagnet connected with inducer on the outter side of the opening. Through the second opening, place a prepared ampoule loaded with a nut wrench,and put a plug in it too. By raising and lowering the leveling pot,we are setting up the initial volume of the burette (preferably as small as possible) By pushing the buttons on the transformer, the electromagnet pulls in the magnet in the external pot, which causes the loaded ampoule to fall to the bottom of the internal pot and break. The sample evaporates and the resulting vapor ejection is equal to the volume change in the leveling pot and the burette. The volume is stabilized by lowering the leveling pot next to the burette. When the volume is stabilized, we read off the final value of the volume. The mesurement is repeated once again as described. Result and conclusion: This experiment helps us to determine the mass and the volume of the organic compound, in the known pressure and temperature conditions. Using those information, we are able to calculate the molar mass of our sample. By comparing the experimental molar mass and the theoretical molar mass, certain disimilarities are visible between the two. Regarless of the small disimilarities, we can conclude that the Victor Meyer method is very reliable.

DETERMINE HEAT OF NEUTRALIZATION OF NaOH AND HCl : ALL PUNJAB BOARD PRACTICALS CHEMISTRY ( FBISE )
 
05:24
SARGODHA BOARD , RAWALPINDI BOARD , FAISALABAD BOARD , MULTAN BOARD . NEUTRALIZATION REACTION : when an acid and a base react to form water and a salt . It involves the combination of H+ ions and OH- ions to generate water. e.g HCl + NaOH ----------- NaCl + H2O acid base salt water HEAT OF NEUTRALIZATION : The change in enthalpy that occurs when one equivalent of an acid and one equivalent of a base undergo a neutralization reaction to form water and a salt . OR The heat released when one mole of H+ ions from an acid and one mole of Hydorxyl ions from a base react to form water . its standard value is 57.32 KJ/mol. STRONG ACID : An acid which completely ionizes in an aqeous solution. e.g hydrochloric acid , sulphuric acid , nitric acid. WEAK ACID : An acid which doesnot completely ionize in aqeous solution. e.g oxalic acid , acetic acid , benzoic acid . Heat of neutralization may vary depending on acids and bases . If a strong acid reacts with a strong base , its value is close to standard i.e 57.32 JK/mol . While if a weak acid or base react , the enthalpy of neutralization is less because these donot dissociate completely in aqeous solution. CALORIMETRY : Study dealing with the changes in energy of the system by measuring the heat exchanged with the surroundings . A calorimeter is a device designed to measure heat of reaction or physical changes and heat capacity . CALORIMETER : - A calorimeter consists of two vessels, outer vessel and an inner vessel. - The space between these vessels acts as a heat insulator and hence there is very little heat exchange in between the inner and outer vessels. - Thermometer measures the temperature of the liquid in the inner vessel. - The stirrer functions in such a way to stir the liquid to distribute the heat in the entire vessel. PROCEDURE - Equimolar solutions of NaOH and HCl were prepared . - Calorimeter was cleaned and dried . - It was then weighed with lid and stirrer . Weight of Calorimeter = 201.69 g - 50 ml of NaOH solution was taken in calorimeter . - Initial temperature was also noted . ------ Initial temperature = 34 'C - 50 ml of HCl solution was added into it with constant stirring . - Weigh the calorimeter again with lid , stirrer and mixture solution . CALCULATIONS : Mass of Calorimter + lid + stirrer = m1 = 201.69 g Mass of Calorimter + lid + stirrer + mixture = m2 = 308.79 g Mass of mixture = m3 = ( m2 - m1 ) = 308.79 - 201.69 = 107.1 g Initial Temperature = T1 = 34 'C Final Temperature = T2 = 39.3'C Rise in Temperature = T2- T1 = 39.3 - 34 = 5.3 'C CALCULATIONS : Specific heat of copper calorimeter = S1 = 0.091 cal/g Specific heat of mixture ( water ) = S2 = 1 cal/g Volume of acid/ base used = 50 ml Molarity of acid/base used = 1 M RESULT : Heat of Neutralization of NaOH and HCl is 56.4 KJ/mol .

From experimental data collected by finding the mass of oxygen gas (our standard) and the mass of other gases in the same volume at the same T and P, and using the standard molar mass of oxygen as 32 amu per molecule or 32 grams per mole, we can calculate the molar mass of any other gas.

Density
 
03:13
Just like all matter water has physical properties that can be measured and calculated. To find the mass of water you will need a beaker and a scale. First find the mass of the empty beaker. Next, fill up the beaker to your desired amount. Then use the scale to find the mass of the filled beaker. To find the mass of just the water, subtract the mass of the empty beaker from the full beaker. Our sample is 100 grams. The volume of water can be measured using a graduated cylinder. Our sample is 100ml. Density is calculated by dividing the mass by the volume. Plug in our measured mass at 100 grams and divide that by our measured volume of 100 ml. Water's density is 1 g/ml. Objects with a density greater than 1g/ml will sink when placed in water. Objects with a density less than one will float when placed in water. If a block has a density of 0.1g/cm3 it will float because it's density is less than 1. Another block with a density of 0.5g/cm3 will also float because its density is less than 1. Notice that more of the block is below the waterline. A block with a density of 0.9g/cm3 is more dense so more of the block will be below the waterline. We can see that as density increases more of the block is below the waterline. Scientists have discovered that the blocks density will tell us exactly where the block will come to rest. If the density is 0.1g/cm3 then 10% will be below the waterline. To calculate where a block will come to rest just convert the density to a percent. Density explains why ice floats. If you freeze water it expands. The black dots represent the atoms in water. No new atoms were are added to the water so because of the expansion there is more room between the atoms. Compared to the atoms in liquid water, the atoms in the ice are not as tightly packed together causing the ice to float. Try calculating density of ice for yourself. If you get a number less than one it will float. You can also predict how much of it will be below the waterline.
