Calculate the ${\mathrm{H}}_3{\mathrm{O}}^{+}$ ion concentration of a solution having a $\mathrm{pH}$ of $10.6$.

The $\mathrm{pH}$ of blood serum is $7.4$. What is the hydrogen ion concentration of blood serum?

Urine has a $\mathrm{pH}$ of $6.0$. If a patient eliminates $1300 \mathrm{mL}$ of urine per day, how many gram equivalents of the acid he eliminates per day?

Lemon juice has a $\mathrm{pH}=2.1$. If all the acid in lemon is citric acid $(\mathrm{H} \mathrm{Cit}.\rightleftharpoons {\mathrm{H}}^{+}+{\mathrm{Cit}}^{-1} )$ and ${\mathrm{K}}_{\mathrm{a}}$ for citric acid is $8.4\times {10}^{-4} \mathrm{mole}/\mathrm{litre}$, what is the concentration of citric acid in lemon juice?

The $\mathrm{pH}$ of $0.1 \mathrm{M}$ solution of an organic acid is $3.0$. Calculate the dissociation constant of the acid.

$0.01 \mathrm{M}$ solution of an organic acid is found to have a $\mathrm{pH}$ of $4.15$. Calculate the concentration of the anion, the ionization constant of the acid and its ${\mathrm{pK}}_{\mathrm{a}}$.

The $\mathrm{pH}$ of $0.005 \mathrm{M}$ codeine $\left({\mathrm{C}}_{18}{\mathrm{H}}_{21}{\mathrm{NO}}_3\right)$ solution is $9.95$. Calculate its ionization constant and ${\mathrm{pK}}_{\mathrm{b}}$.
