The objective of this experiment was to learn the process of recrystallization and how this process removes the impurities from a pure solid compound. The methods used to achieve this objective were also hot vacuum filtration in order to remove suspended solid impurities‚ and isolating the pure acetanilide. In the next lab‚ percent recovered was obtained through weighing the acetanilide sample as well as comparing its melting point range. In this experiment‚ the sample‚ acetanilide was weighted

Discussion/Conclusion In this experiment‚ t-pentyl chloride was synthesis by reacting concentrated hydrochloric acid using nucleophilic substitution sn1. In the substitution reaction the Hydrogen in HCl protonated the alcohol group in t-pentyl alcohol and turned it to a good leaving group (H2O). a tertiary carbon cation was formed. a nucleophilic attach of the negative Cl- attacked the carbon cation forming t-pentyl chloride [7]. As the reaction proceeded‚ extraction and distillation techniques

When you mix vinegar and baking soda you get a chemical change. The chemical property that causes this is called reactivity. Baking soda’s chemical formula is NaHCO3 and it’s a compound. Vinegar’s chemical formula is CH3COOH and it’s a compound. The problem of this is how much baking soda‚ added to 10mL of vinegar‚ will cause a film canister rocket to shoot the furthest. I think 5mL will shoot the farthest because there will be more for the baking soda build up in the canister. The independent variable
