At 25 °C, how many dissociated H+ ions are there in 341 mL of an aqueous solution whose pH is 11.39? Chemistry Acids and Bases pH calculations 1 Answer Al E. Nov 21, 2017 Approximately #8.36*10^11# dissociated #H^(+)# ions are in the described solution. Explanation: #10^(-11.39) approx 4.07*10^-12M# #(4.07*10^-12mol)/L * 0.341L * (6.02*10^23ions)/(mol) approx 8.36*10^11ions# Answer link Related questions How do you determine ph of a solution?
