WebbA 0.15 M solution of butanoic acid, CH3CH2CH2COOH, contains 1.51*10-3 M H3O+. What is the Ka of butanoic acid? Ka = 1.54*10^-5 Refer to Lesson 11.1 The weak acid HQ has a pKa of 4.89. (a) Calculate the [H3O+] of 3.5*10-2M HQ. (b) Calculate the [OH-] of 0.65 M HQ. (a) [H3O+] = 6.7*10^-4 M (b) [OH-] = 3.5*10^-12 M Refer to Lesson 11.7 WebbThe correct option is A Acidic. pH = −log[H+] or, H+ =10(−pH) As, pH = 0 or, [H+] = 10(−0), then [H+]= 1. Or, we can say that concentration of [H+] = 1mol/litre. The concentration of [H+] ions and acidity of a solution are directly proportional to each other. Since the concentration of [H+] ions is very high, the solution will be highly ...
