Understanding such calculations is crucial in determining the acidity or basicity of a solution.- **Part (a)** deals with a weak acid salt (sodium chloroacetate) whose \([\text{H}_3\text{O}^+]\) is determined by its \(K_a\).- **Part (b)** requires converting a weak base constant (\(K_b\)) into its corresponding acid constant to find \([\text{H}_3\text{O}^+]\).- **Part (c)** involves a strong acid (\(K_a\)
