1. Solubility in WATER Check solubility of four solutes in water (H2O). For each solute record how many teaspoons dissolved in 1/2 cup of water. NaCl: Start out with 4 small glasses (cups) and add 1/2 cup of water to each. Put 1/2 level teaspoon (tsp) of salt (NaCl) into the first cup and stir. If it dissolves within 1 minute; add another 1/2 tsp of salt and stir. Count the number of 1/2 tsps you are adding. Repeat until...

please answer all parts I am trying to check my
answers.
Recrystallization of Acetanilide Recrystallization is an important method used by chemists to purify solid compounds. When a chemist conducts a chemical reaction as shown in Scheme 1, it will rarely go to 100% completion, and will frequently produce byproducts. These byproducts and some of the unreacted starting materials will be present in the end as impurities. Chemists need ways to remove these unwanted impurities so they can isolate their...
