To solve the problem, we need to find the initial molar concentration ratio of two weak acid solutions, \( HA \) and \( HB \), such that they have the same pH. Given that the ratio of their dissociation constants \( K_a \) is \( 4:1 \), we can denote: - \( K_a (HA) = 4K \) - \( K_a (HB) = K \) ### Step-by-Step Solution: 1. **Understanding the Dissociation of Weak Acids**: ...
