Solved 2. What is the pH of the acid at the concentration - Chegg
WebSo the Ka is equal to the concentration of the hydronium ion. And since there's a coefficient of one, that's the concentration of hydronium ion raised to the first power, times the concentration of the acetate anion also raised to the first power, divided by the concentration of acidic acid raised to the first power. WebClearly, ka =/ 1/Kb : one has H3O+ and the other has OH- (the others are in the equation, but in very very very small quatities so we ignore them) For example, HCN is an acid and … burris cars

WebJun 1, 2015 · By definition, the acid dissociation constant, Ka, will be equal to Ka = [H 3O+] ⋅ [A−] [H A] If you have a 1:1 mole ratio between the acid and the hydronium ions, and between the hydronium ions and the conjugate base, A−, then the concentration of the latter will be equal to that of the hydronium ions. [A−] = [H 3O+] hammocks apartments orchard park
