For a weak acid,the $\alpha$_HA____________________ and the $\alpha$_A-____________________ with increased pH.

Question

Quizplus · Accepted Answer

For a weak acid, as the pH increases, the concentration of H+ ions decreases. This leads to a shift in the equilibrium towards the dissociated form of the acid, resulting in an increase in the concentration of A- ions and a decrease in the concentration of HA molecules. Therefore, the fraction of acid that is dissociated (alpha) decreases while the fraction of its conjugate base that is formed increases. Thus, option D is the correct answer.

For a Weak Acid,the α\alphaα HA____________________ and The α\alphaα A-____________________ with Increased PH

For a Weak Acid,the $\alpha$ _HA____________________ and The $\alpha$ _A-____________________ with Increased PH
