Calculate the mole ratio in which salt and acid are to be mixed in ord

1.	Calculate the mole ratio in which salt and acid are to be mixed in order to get a buffer solution of 5? [pK_(a) of acid = 4].
Answer» SOLUTION :Henderson's EQUATION `pH=pK_(a)+"log"(["SALT"])/(["ACID"])` `5=4+"log"(["Salt"])/(["Acid"])` `1="log"(["Salt"])/(["Acid"])` `1="log"10/1`
