WebThe pOH of a solution is defined as the negative log10 [OH¯] Conversely, [H3O+] = 10-pH and [OH¯] = 10-pOH The pH of a neutral solution is therefore 7. (-log [1 x 10 -7] = 7) The sum of the pH and pOH must always equal 14. This is because the –log K W = -log (1 x 10 -14) = 14. More generally, acid dissociation constants (K a) are of the form: WebLista de exercícios. 2) Encontre as concentrações ini ciais dos ácidos ou bases fracos em cada uma das. 3) Calcule K a e pK a ou K b e pK b para as seguintes soluções em água: a) 0,010 mol L -1 de ácido mandélico (anti-séptico) com pH = 2,95. 4) A porcentagem de ionização do ác ido benzóico em uma solução 0,110 mol L -1 é 2,4%.
