WebJan 30, 2024 · Calculate the pH from the equilibrium concentrations of [H 3 O +] in Example 4. Solution Given: [HOCl]=0.199 [H 3 O + ]=8.4 x 10 -5 [OCl-]=8.4 x 10 -5 Step 1: Use the formula using the concentration of [H 3 O +] to find pH (21) p H = − log [ H 3 O +] = − log ( 8.4 x 10 − 5) = 4.08 References WebThe pH dictates the free chlorine species present in aqueous solutions. At a pH of between 5-6, the chlorine species is nearly 100% hypochlorous acid (HOCl). As the pH drops below 5, it starts to convert to Cl2 (chlorine gas). Above a pH of 6, it starts to convert to the hypochlorite ion (OCl-). fly for humanity
