The Ion Product of Water H 2 O (l) H+ (aq) + OH- (aq) [H+][OH-] Kc = [H 2 O] = constant Kc[H 2 O] = Kw = [H+][OH-] The ion-product constant ( ﺛﺎﺑﺖ ﺍﻟﻨﺎﺗﺞ ﺍﻷﻴﻮﻧﻲ Kw) is the product of the molar concentrations of H+ and OH- ions at a particular temperature. ﻋﻨﺪ ﺩﺭﺟﺔ ﺣﺮﺍﺭﺓ ﻣﻌﻴﻨﺔ Solution Is [H+] = [OH-] neutral At 250 C +] > [OH-] [H acidic + 14 Kw = [H ][OH ] = 1. 0 x 10 [H+] < [OH-] basic

What is the concentration of OH- ions in a HCl solution whose hydrogen ion concentration is 1. 3 M? Kw = [H+][OH-] = 1. 0 x 10 -14 [H+] = 1. 3 M -14 K 1 x 10 w -15 M = = 7. 7 x 10 [OH-] = [H+] 1. 3
