Answer #1

Solution :-

When the Na2CO3 and HCl are used to make the buffer

Then the reactions which are taking place are as follows

CO3^2- ion will acts as base and produce the HCO3^- ion as the conjugate acid

Therefore after mixing the HCl with NaCO3 we will get the HCO3^- and CO3^2- ions in the solution which will act as buffer system.

Therefore in the buffer if the acid is added then it will react with the CO3^2- ion to form the HCO3^- and maintain the pH

And if the base is added in the buffer then it will react with the HCO3^- ion to form the CO3^2- ions and maintain the pH
