Complete the $K_{sp}$ expression for $\text{Cr(OH)}_3$, and include the units.
At 298 K, Calculate the solubility of $\text{Cr(OH)}_3$ in pure water, in $\text{g dm}^{-3}$. Show your working.
Why is $\text{Cr(OH)}_3$ less soluble in $0.100\ \text{mol dm}^{-3}$ NaOH than it is in pure water? Explain this observation.
At 298 K, Calculate the pH of $0.100\ \text{mol dm}^{-3}$ $\text{CH}_3\text{CH}_2\text{CH}_2\text{COOH}$. Show your working.
At 298 K, Calculate the pH of $0.100\ \text{mol dm}^{-3}$ NaOH.
$5.00\ \text{cm}^3$ of $0.100\ \text{mol dm}^{-3}$ NaOH is added to $10.00\ \text{cm}^3$ of $0.100\ \text{mol dm}^{-3}$ $\text{CH}_3\text{CH}_2\text{CH}_2\text{COOH}$. Calculate the pH of the resulting solution. Show your working.
An aqueous solution of volume $80.0\ \text{cm}^3$ that contains $0.704\ \text{g}$ of $\text{CH}_3\text{CH}_2\text{CH}_2\text{COOH}$ is shaken with $100\ \text{cm}^3$ benzene, $\text{C}_6\text{H}_6$. At equilibrium, $0.556\ \text{g}$ of $\text{CH}_3\text{CH}_2\text{CH}_2\text{COOH}$ is present in the $100\ \text{cm}^3$ of $\text{C}_6\text{H}_6$. Calculate the partition coefficient, $K_{pc}$, of $\text{CH}_3\text{CH}_2\text{CH}_2\text{COOH}$ between $\text{C}_6\text{H}_6$ and water. Show your working.
