The ionic product of water kw

WebWhen utilizing the ion product of water (Kw = 1 x 10-14), an increase in [H+] would cause a (n) in [OH-]. Question options: A) increase B) no change C) decrease D) can not be determined C) decrease The Henderson-Hasselbalch equation: A) does not explain the behavior of di- or tri-basic weak acids. WebThe pH at the end point of this reaction is 11.8 Use this pH value and the ionic product of water, Kw = 1.0 × 10-14 mol2 dm-6, to calculate the concentration of hydroxide ions at the end point of the reaction. [H+] = 10-pH = 1.58 × 10-12 Kw = [H+] [OH-] therefore [OH-] = Kw / [H+] Therefore, [OH-] = 1 × 10-14/1.58 × 10-12 = 6.33 × 10-3 (mol dm-3) .
