The value of Ka for acetylsalicylic acid will be calculated as Ka=(x+a)²/x.
What is Ka?
Ka is known by the name of acid dissociation constant and for weak acid HA at equilibrium Ka will be calculated as:
Ka = [H⁺][A⁻] / [HA]
Chemical equation with ICE table for the acetylsalicylic acid will be shown as:
C₉H₈O₄(aq) + H₂O(l) ⇄ C₉H₇O₄(aq) + H₃O⁺(aq)
Initial: x 0 0
Change: -a +a +a
Equilibrium: x-a x+a x+a
So, Ka for acetylsalicylic acid will be calculated by putting values on the above equation as:
Ka = [x+a][x+a] / [x-a]
Value of a is negligible as compared to the value of x of acetylsalicylic acid so the term x-a becomes x and equation will be written as:
Ka = (x+a)² / x
By knowing the all values of concentration we can calculate the value of Ka.
Hence Ka value for acetylsalicylic acid will be calculated by using the formula as Ka = (x+a)² / x.
