The table shows the concentrations and $\text{pH}$ readings for the aqueous solutions of two compounds, $X$ and $Y$. Each compound may be either an acid or a base. For $X$: concentration $= 2\ \text{mol dm}^{-3}$, $\text{pH} = 6$ For $Y$: concentration $= 2\ \text{mol dm}^{-3}$, $\text{pH} = 9$ Student P decided that $X$ is a strong acid. Student Q decided that the degree of dissociation is smaller in $X(aq)$ than in $Y(aq)$. Which student(s) are correct?
- Aboth P and Q
- Bneither P nor Q
- CP only
- DQ only
