Best ResponseYou've already chosen the best response.0okay i cant figure out how to do it with 3 but this is with 2, you you could just replace the 2 with 3 and do the same steps: HBr is a strong acid so it dissociates completely in water: HBr + H2O = H3O+ + Br 1mol HBr = 1mol H3O+ [HBr] = 2.6*10^2. Therefore: [H3O+] = 2.6*10^2 What is pH? pH = log [H3O+] pH = log (2.6*10^2) pH = 1.59 What is [OH] pH + pOH = 14.00 pOH = 14.00pH pOH = 14.00  1.59 pOH = 12.41 [OH] = 10^pOH [OH] = 10^12.41 [OH] = 3.85*10^13 There is a very simple way to work out [OH] [H3O+] * [OH] = 10^14 [OH] = (10^14) / (2.6*10^2) [OH] = 3.85*10^13 I did both methods because OI am not sure what you have been taught.

Best ResponseYou've already chosen the best response.1@vera_ewing you want to get pH from [ OH ] ? not pOH right?

Best ResponseYou've already chosen the best response.1@vera_ewing We need to convert it from [OH] to [ H+ ] from [H + ] we can get the value of pH by taking the logarithm

Best ResponseYou've already chosen the best response.1@jcoury I found the site where you copy pasted your answer here, that is indeed off topic, and does not help in any form. Please avoid this type of actions. thanks reference https://answers.yahoo.com/question/index?qid=20100809235159AAcCjxE
