Solution of
Concept Introduction:
Salts formed from alkali metal cation and halogens as anions are neutral. This is because the cation acts as spectator ion while the anion is not strong enough to react with water as halides are conjugate bases of strong hydrohalic acids. Thus salts such as

Chemistry: Principles and Practice
- You are asked to determine whether an unknown white solid is acidic or basic. You also need to say whether the acid or base is weak or strong. You are given the molar mass of the solid and told that it is soluble in water. Describe an experiment that you can perform to obtain the desired characteristics of the white solid.arrow_forwardThe weak base, CIO (hypochlorite ion), is used in the form of NaCIO as a disinfectant in swimming pools and water treatment plants. What are the concentrations of HCIO and OH and the pH of a 0.015 M solution of NaCIO?arrow_forwardPyruvic acid, which is produced in metabolic reactions, has the structure Would you predict that this acid is a mono-, di-, tri-, or tetraprotic acid? Give your reasoning.arrow_forward
