Choose the correct statementA. pH of acidic buffer solution decrease if more salt is addedB. pH of acidic buffer solution increeses if more salt is addedC. pH of basic buffer decreases if more salt is addedD. pH of basic buffer increases if more salt is added |

Answer» Correct Answer - B::C (b) is correct because `pH=pH_(a)+log""(["Salt"])/(["Acid"])` for acidic buffer. If [Salt] increase, pOH will increase, pH will decrease as `pH=14-pOH` Therefore © is correct but (d) is wrong. (a) is correct explained below `pH=pK_(a)+log""(["Salt"])/(["Acis"])` If [salt] increase, pH will increase. |
