| [a] \[0.01\,\,M\,\,C{{H}_{3}}COONa\] |
| [b] \[0.01\,\,M\,\,NaHC{{O}_{3}}\] |
| [c] Buffer of 0.01 \[M\,\,C{{H}_{3}}COONa\] and 0.01 \[M\,\,C{{H}_{3}}COOH\] |
| [d] \[0.01\,\,M\,\,C{{H}_{3}}COON{{H}_{4}}\] |
A) a, b, d
B) b, c, d
C) a, d
D) a, c, d
Correct Answer: B
Solution :
pH of [I] Salts of weak acid and weak Base as \[RCOON{{H}_{4}}\] [II] amphiprotic Ions as \[HCO_{3}^{-},\text{ }H{{S}^{-}}\] [III] Buffer solutions are not affected by dilution
