Question

Calculate pH in the end points and molarity of HCl and CH3COOH?

Answer 1

CH3COOH has a pH of 2.64

Molarity of Hydrochloric Acid (HCl) = 12.1

Answer 2

• pH of a solution depends upon the hydrogen ion concentration.
• pH of a solution depends upon the hydrogen ion concentration.HCl is a strong acid and it will be almost completely (100%) ionised even at appreciable concentration.
• pH of a solution depends upon the hydrogen ion concentration.HCl is a strong acid and it will be almost completely (100%) ionised even at appreciable concentration.But CH3-COOH being a weak acid will be weakly ionised at even dilute concentration. Acetic acid will be nearly 3- 5% dissociated at 0.1 M concentration.
• pH of a solution depends upon the hydrogen ion concentration.HCl is a strong acid and it will be almost completely (100%) ionised even at appreciable concentration.But CH3-COOH being a weak acid will be weakly ionised at even dilute concentration. Acetic acid will be nearly 3- 5% dissociated at 0.1 M concentration.Let us consider HCl and CH3-COOH solutions of 0.1M concentration.
