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...
