Calculate the pH of a 0.10 M solution of acidic acid HC2H3O2(aq) at 25 °C. Ka for HC2H3O2 = 1.8×10−5 at 25 °C g
Answers: 2
![Ka = \frac{[CH3COO^{-}] [H^{+}]}{[CH_3COOH]}\\\\](/tpl/images/1354/5896/b6175.png)
![1.8\times 10^{-5} = \frac{x^2}{0.10}\\\\x^2 = 1.8 \times 10^{-6}\\\\x = 1.34 \times 10^{-3}\\\\pH = -\log [H^{+}]](/tpl/images/1354/5896/b9098.png)
![[H^{+}] = x = 1.34 \times 10^{-3}](/tpl/images/1354/5896/38a1b.png)
