predict the pH of an aqueous solution that is 0.00378 molar in HBr
Answered by DrBob222
HBr is a strong acid; therefore, it ionizes 100%. pH = -log(H^+).

can we go over this one?
Answered by katie
how do i do this one
Answered by DrBob222
HBr is one of the strong acids. A strong acid ionizes 100%. Therefore, the H^+ concentration is the same as the HBr concentration. You are given the HBr concn, plug that into the equation, and out pops the pH. I shall be happy to check your answer.
