Four different acids are described below. • Hydrochloric acid at a concentration of $0.0100\ \text{mol dm}^{-3}$ has a pH of $2$. • Ethanoic acid at a concentration of $0.0100\ \text{mol dm}^{-3}$ has a pH of $3.4$. • Hydrobromic acid, HBr, is a strong acid. • Ethanoic acid is a slightly stronger acid than trimethylethanoic acid. State the pH values for $0.0100\ \text{mol dm}^{-3}$ HBr and $0.0100\ \text{mol dm}^{-3}$ trimethylethanoic acid.
- ApH $2$ and $3.3$
- BpH $2$ and $3.5$
- CpH $3.4$ and $3.3$
- DpH $3.4$ and $3.5$
