1.	Which of the following solution will have no effect on pH dilution?
Answer» `0.3M CH_3 COOK` ` 0.4 M CH_3 COONH_4` ` 0.2 MNH_4 OH+ 0.2 M NH_4 Cl` ` 0.3 H_2CO_3 +0.3 M NaHCO_3` SOLUTION :(a) `pH = 7+((pKa+LOG c )/( 2 )) `depends on C (b)pH = 7+ ` ((pKa- pKb)/( 2 )) = 7 ` does not DEPEND C ( c )`pH =pKb + log ""(S)/(B)= pKb`doesnot depend on C (d)`pH=pKa_1 + log "" (S)/(A)= pKa_1 `, doesnot depend on C
