To solve the problem, we need to find the ratio of \([HA^+]\) in a 1L solution of \(0.1M H_3A\) before and after the addition of \(0.1\) moles of \(HCl\). The dissociation constants given are \(K_{a1} = 10^{-5}\), \(K_{a2} = 10^{-8}\), and \(K_{a3} = 10^{-11}\). ### Step-by-Step Solution: 1. **Initial Concentration of \(H_3A\)**: - We start with a \(0.1M\) solution of \(H_3A\). The initial concentration of \(H_3A\) is \(0.1M\). 2. **Dissociation of \(H_3A\)**: ...
