Calculation of pH of 0.1 Molar Solution of Acid HA with Dissociation Constant of 1×10^-5
Step 1: Write the dissociation equation for the acid HA
HA ⇌ H+ + A-
Step 2: Write the expression for the dissociation constant of the acid HA
Ka = [H+][A-]/[HA]
Step 3: Substitute the given values in the expression for Ka
1×10^-5 = [H+][A-]/[0.1]
Step 4: Assume that the concentration of H+ and A- ions formed from dissociation of HA is x
1×10^-5 = x^2/0.1
Step 5: Solve for x
x = √(1×10^-5 × 0.1) = 1×10^-3
Step 6: Calculate the pH of the solution using the concentration of H+ ions
pH = -log[H+]
pH = -log(1×10^-3)
pH = 3
Therefore, the pH of 0.1 molar solution of the acid HA with dissociation constant of 1×10^-5 is 3.
