When a stress is applied to a system at equilibrium, the system will respond by shifting in the direction that opposes/ minimizes the effect of the stress.
• This stress could be the addition or removal of a product or reactant, changes in the concentration of the products or reactants, or a change in temperature.

pH is calculated by taking negative logarithm of hydrogen ion concentration.
According to stoichiometry,
1 mole of gives 1 mole of
Thus moles of
gives =
moles of
Putting in the values:
Thus the pH will be 3.87
