Find ph from kb
WebNov 28, 2024 · kb = [bh +][oh-]/[b] From the pH = 9.54, we can find the [H + ] and from that we can find the [OH - ]. Since [OH - ] = [BH + ], and we are given the initial [B], we have all we need to calculate the Kb. WebIn that same sense, Ka * Kb can be conceived as multiplying the products of both Ka and Kb and dividing by the reactants of both Ka and Kb. Reverse the process you use for writing equilibrium expressions: multiplication = add to the products, division = add to …
