pH of K2S solution is: - Chemistry Questions - Toppr

WebbSolution. According to the stoichiometry of the dissolution equation, the fluoride ion molarity of a CaF 2 solution is equal to twice its calcium ion molarity: [F −] = (2molF − /1molCa2 +) = (2)(2.15 × 10 − 4M) = 4.30 × 10 − 4M. Substituting the ion concentrations into the Ksp expression gives.

WebbThe pH value of 0. 1 M NaOH solution is (when there is a given reaction [H +] [O H −] = 1 0 − 1 4) 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 pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. … cannot resolve symbol gin
