Classify NaOH as a strong base, weak base, strong acid, or weak acid. Then answer the following question. What is the pH of a 7.8 x 10-SM NaOH(aq) solution? a. 4.1 b. 9.5 C. 9.9 d. 4.5 e. 13.0
Calculate the pH of a solution containing a salt AcNa derived from a strong base (NaOH) and a weak acid (AcH), like CH3COONa, KF, NaNO2 and so on. In this case two processes have to be considered: 1. Dissociation of the salt, within the assumption that the salt is a strong electrolyte: AcNa → Ac- + Na+, for instance: CH3COONa → CH3COO- + Na+ 2. the hydrolysis of the water Ac- + H2O ⇌ AcH + OH-, for example:...
