Question

Conside Tollowing data on some weak acids and weak bases: acid base name formula name formula hypochlorous acid HClO 3.0 x10-8 aniline C H5NH2 4.3 x 10-10 methylamine CH3NH2 4.4 x 10-4 nitrous acid HNO2 4.5 x 10-4 Use this data to rank the following solutions in order of increasing pH. In other wolds, select al the solution that will have the next lowest pH, and so on. solution PH 0.1 M KCI 2 9 0.1 M C6H5NH2CI 0.1 M NaNO2 1 (lowest) 0.1 M KCIO 4 (highest) : Explanation Check

Answer 1

As given compounds are salt solution. So acidic salts have pH greater than 7 and acidic salts have pH less than 7. pH of neutral is 7.

0.1 M KCl = 2

0.1 M C6H5NH3Cl = 1

0.1 M NaNO2 = 3

0.1 M KClO= 4
