1.	A buffer solution contains a weak acid HA and A . When small quantity of NaOH is added, to keep p^(H)as constant. which of the following reaction takes place?
Answer» ` HA to H^(+) A^(-) ` ` H^(+) A^(-) toHA` ` HA+ OH^(-) to H_2O +A^(-) ` `A^(-) +H_2O to HA+ OH^(-) ` Solution :NaOHadded is a base hence acid COMPONENT of the buffter . `HA+ OH^(-)to H_2O+A^(-) `
