Ph of 10 -7 naoh
WebJul 7, 2016 · The pH is 7.08. Explanation: The base is so dilute that we must also consider the OH- that comes from the autoionization of water. H2O ⇌ H+ +OH- Kw = [H+][OH-] = 1.00 × 10-14 We start by noting that charges must balance. If the OH- comes from NaOH, then [OH-] = [H+] + [Na+] The H+ comes from the autoionization of water, so [H+] = 1.00× 10-14 … WebpOH = 14-pH = -log10 [OH-] So pOH = -log10 {10] =. log10 of 10 = 1. So -log [OH] = -1. Molarity of NaOH = molarity of OH- because it is virtually completely ionized in water …
