Question

An aqueous solution of ________ will produce a basic solution.

Answer 1

An aqueous solution is that in which the solvent used is water. The salts formed by the reaction of a strong base and weak acid can be dissolved in water to form basic solution. Examples of these basic salts are NaF, NaCO3, etc. 

Answer 2

The aqueous solutions of NaHS, KHCO3 and NaF has the ability to produce a basic solution. By definition, an aqueous is a type of solution in which its solvent is water. NaHS is Sodium hydrosulfide which is a reagent, KHCO3 is potassium bicarbonate used as a food ingredient, and sodium fluoride for teeth cavities.
