Step 1. Calculate [H⁺]

HC₂H₃O₂⇌ H⁺+ C₂H₃O₂^-

^{$K_{a} = \frac{products}{reactants} K_{a} = \frac{[H^{+}] [C_{2} H_{3} {O_{2}}^{-}]}{[{HC}_{2} H_{3} O_{2}]} = 1.8 \times 10^{- 5} \frac{[x] [x]}{[0.250]} = 1.8 \times 10^{- 5} \sqrt{x^{2}} = \sqrt{(1.8 \times 10^{- 5}) (0.250)}$}

x = 2.12x10^-3M = [H⁺]
