Document Summary

Unit 7: module 3 - acid-base chemistry iii ph of salt solutions. If we want to know what the ph of a 0. 1m nacl solution is: first recognize that nacl is soluble in water the salt would dissociate to form sodium ions and chloride ions. Sodium ions are hydrated with water molecules, but there is no reaction between them. Sodium ions come from sodium hydroxide, which is a strong base. Chloride ions could have come from hcl, which is a strong acid. A strong acid and a strong base neutralize one another and the result is a neutral salt from the spectator ions and water. If ammonium chloride dissolves in water, we get ammonium and chloride ions: chloride will not react with water, but the ammonium ion is a weak acid that reacts with water to form an equilibrium producing ammonia and h3o+
