NaCl → Salt formed by reaction of NaOH and HCl 3 NaNO → Salt formed by reaction of NaOH and 3 HNO Thus, in both cases, we will not expect hydrolysis as both acid and base from which NaCland 3 NaNO are formed are strong and pH is equal to7. Among 2 4 H SO and 2 H S , 2 4 H SO is stronger than 2 H S thus pH of 2 4 H SO < pH of 2 H S . Thus, correct option is 3 2 2 4 0.01 M NaCl 0.01 M NaNO 0.01 M H S 0.01 M H SO
