However the value of this expression is very high, because HBr What is the value of K_{b} for C_{2}H_{3}O_{2}^-. What is the value of it"s k_a? A 0.200 M solution of a weak acid has a pH of 3.15. of HPO,2 in the reaction Each compound has a characteristic ionization constant. Determine the acid ionization constant (Ka) for the acid. What is the [OH^-] ion in an aqueous solution that has a pH of 11.70? On this Wikipedia the language links are at the top of the page across from the article title. For a solution with an (H+) of 10-4 M, what would be the value of (OH-), pH, and pOH, respectively? So, assume that the x has no effect on 0.240 -x in the denominator. A concentration of 0.020M in aqueous solution gives a pH of 4.93 what is the Ka?
