Salt, in chemistry, substance produced by the reaction of an acid with a base. A salt consists of the positive ion (cation) of a base and the negative ion (anion) of an acid. In this lecture you will learn how to prepare salts using the excess method. A soluble salt can be prepared by reacting an acid with a suitable insoluble reactant including a metal, a metal oxide, a carbonate. To make a soluble salt from an acid and an insoluble reactant: Add some dilute hydrochloric acid to a beaker. Add powdered insoluble reactant to some acid in a beaker, one spatula at a time, stirring to mix. The mixture will effervesce. Continue adding powder until some unreacted powder is left over - it is in excess. Filter the mixture in the beaker to remove the excess powder. Allow the water in the solution to evaporate (by heating and/or leaving for a few days) to obtain pure dry crystals of the salt.
