A and B are powders, A is insoluble while B dissolves to give a pH 3 solution. Mixing A and B gives bubbles or effervescence and
a clear solution. a) which is the acid? b) if the other substance is a carbonate, name the gas given off. c) even though A is insoluble a clear solution is given off, explain why.
a) B dissolves to produce an acid. An acid, according to the Bronsted-Lowry theory, dissolves in an solution to give an acid solution of a pH less than 7 on a pH scale.
b) carbonates gives a gaseous effervescence. The gas given off is carbon dioxide
c) The solution is a salt of an acid. This is in an aqueous solution.
