4-nitroaniline had a percent recovery of 18.67% and naphthalene had a percent recovery of 80%. Naphthalene had a relatively high percent recovery‚ and the loss of product can be explained by error inherent. The low percent recovery of 4-nitroaniline is mainly due to the fact that anhydrous sodium sulfate was accidently added to the flask. Therefore‚ some product was lost as the aqueous solution with the protonated 4-nitroaniline reacted with the drying agent. However‚ more errors to explain the results

1. Diffusion and Osmosis‚ June 4‚ 2013 2. Purpose: The purpose of this lab is to help give visual understanding of diffusion which is a solution of high concentration spontaneously (no energy required) moving to an area of low concentration. Also taking a look at osmosis‚ which is the movement of chemicals across the cell membrane. Osmosis requires some type of energy to be put in for this to happen. After these experiments we should have a better idea and visualization of how chemicals transfer

During the experiments a few problems were encountered. One of the chemicals provided differed slightly from chemical description in the lab manual. The lab manual called for the chemical NH3 which is Ammonia. The chemical provided was an Aqueous Ammonia solution of NH4OH. When holding up the solution of AgNO3 and NH4OH to a light source for 5 minutes it was observed that no reactions took place despite the information contained in the lab manual. Also while testing the household chemical Brite‚ It was observed that the Bromthymol Blue changed to a green color that was not

LS Separation of Mixtures and Solids Purpose: To become familiar with the separation of mixtures of solids Hypothesis: I will be able to separate the materials using a variety of different methods. First‚ separate the iron fillings using a magnet. Second‚ I will put the rest of the solution into water and separate the insoluble sand from the soluble salt and benzoic acid. Third‚ I will filter out the benzoic acid when crystalized. Lastly‚ I will evaporate the water away leaving crystallized

Combustible Liquids (Examples: alcohols‚ esters‚ ethers‚ ketones) Vapors from flammable and combustible liquids can mix with air and burn if they contact an ignition source. Possible ignition sources include hot electrical wires‚ hot surfaces‚ open flames‚ hot particles and embers‚ and sparks. The lowest temperature at which a liquid releases enough vapor to start burning is called the flash point. The flash point is what distinguishes a flammable liquid from a combustible liquid. Flammables:
