Write a balanced equation showing how this can occur.Dissolving $\mathrm{K}_{2} \mathrm{CO}_{3}$ in water gives a basic solution. What is the hydronium ion concentration of the solution?What is the pH of a 0.0015 M solution of $\mathrm{Ba}(\mathrm{OH})_{2} ?$The $\mathrm{pH}$ of a solution of $\mathrm{Ba}(\mathrm{OH})_{2}$ is 10.66 at $25^{\circ} \mathrm{C} .$ What is the hydroxide ion concentration in the solution? What is the value of $K_{\mathrm{a}}$ ?
If you have a 0.15 M aqueous solution of the amine, calculate the concentrations of $\left[\mathrm{H}_{3} \mathrm{NCH}_{2} \mathrm{CH}_{2} \mathrm{NH}_{3}\right]^{2+}$ and $\mathrm{OH}^{-}$Which should be the stronger acid, HOCN or HCN? Calculate the concentrations of $\mathrm{H}_{3} \mathrm{O}^{+}, \mathrm{OH}^{-}$ HCN, and $\mathrm{Na}^{+}$ in a solution prepared by dissolving 10.8 g of NaCN in enough water to make $5.00 \times 10^{2} \mathrm{mL}$ of solution at $25^{\circ} \mathrm{C}$.The sodium salt of propanoic acid, $\mathrm{NaCH}_{3} \mathrm{CH}_{2} \mathrm{CO}_{2}$ is used as an antifungal agent by veterinarians.

At more basic pH values, the amine proton is dissociated.How can water be both a Bronsted base and a Lewis base?
)$A hydrogen atom in the organic base pyridine, $\mathrm{C}_{5} \mathrm{H}_{5} \mathrm{N},$ can be substituted by various atoms or groups to give $\mathrm{XC}_{5} \mathrm{H}_{4} \mathrm{N},$ where $\mathrm{X}$ is an atom such as Cl or a group such as $\mathrm{CH}_{3}$.
