1.	Equal volumes of solutions with pH = 4 and pH = 10 are mixed. Calculate the pH of the resulting solution ?
Answer» Solution :pH = 4 means `[H^(+)] = 10^(-4)` M and pH = 10 means `[H^(+)]=10^(-10)M or [OH^(-)]=10^(-4)M`. THUS, they will EXACTLY neutralise each other and pH of the resulting solution will be = 7 .
