1.	It is found that 0.01 M solution of four sodium salts Na, Nal, NaC and NaD have the following pH values: (i) NaD - 10.0 (ii) NaC = 9.0 (iii) NaB - 8.0 (iv) Na4 - 7.0 Which of the corresponding acids is strongest?
Answer» NAA NaB NaC NAD Solution :`pH = 10`(NaD )showsthat thesolutionin stronglybasic i.e., NaDis asaltofstrongbaseandweakacid SimilarlypH=9and pH = 8refertobasicsolution But pH =7 (NaA) showsthat thesolutionin neutrali.e.,NaA is a saltofstong acidacidstrongbase .
