WebStep 1/1. To solve this problem, we need to calculate the concentrations of H+ and OH- in the solution and use the equation for pH: pH = -log [H+] First, we need to determine which acid is the stronger acid. HBr has a lower pKa value (-9) compared to the Ka value of HOCl (2.9x10-8), which means that HBr is the stronger acid and will dissociate ...
