Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Question

**Buffer System Design**

A \( \text{HCN / NaCN} \) buffer system is to be constructed that is also 0.048 M in \( \text{Mg}^{2+} \).

### Objective

Determine the minimum \([\text{HCN}]/[\text{CN}^-]\) ratio that must be maintained to prevent the formation of magnesium hydroxide precipitate.

\[
\frac{[\text{HCN}]}{[\text{CN}^-]}_{\text{minimum}} = \boxed{ \ }
\]

#### Explanation:

This problem involves calculating the minimum concentration ratio of components in a buffer solution to avoid precipitation of magnesium hydroxide when the concentration of magnesium ions \( (\text{Mg}^{2+}) \) is known.
