Answer -
When HCl is added to the solution, theconcentration of H+ ions will increase. Therefore, theequilibrium will shift in the backward direction i.e., dissociation of aceticacid will decrease.
Case I: When 0.01 M HCl is taken.
Let x be the amount ofacetic acid dissociated after the addition of HCl.
As the dissociation of a very small amountof acetic acid will take place, the values i.e., 0.05 – x and0.01 + x can be taken as 0.05 and 0.01 respectively.
Case II: When 0.1 M HCl is taken.
Let the amount of acetic acid dissociated inthis case be X. As we have done in the first case, theconcentrations of various species involved in the reaction are:
