Salts that produce hydroxide ions when dissolved in water are called alkali salts and salts that produce hydrogen ions when dissolved in water are called acid salts. The British men in the business of colonizing the North American continent were so sure they owned whatever land they land on (yes, thats from Pocahontas), they established new colonies by simply drawing lines on a map. A physical change as salt is dissolved in water does not affect mass. For example, laboratory studies of water solubilities for PFOS indicate that solubility decreases when the water salt content increases (3M Company 2000).
