Interpretation Introduction

To determine: If the calcium fluoride is precipitated when $\text{Ca}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ solution of given concentration and volume is added to a solution of $\text{KF}$ solution of given concentration and volume.

Interpretation: Whether the calcium fluoride is precipitated when $\text{Ca}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ solution of given concentration and volume is added to a solution of $\text{KF}$ solution of given concentration and volume is to be stated.

Concept introduction: The product of concentration of salt ions raised to power of the coefficients of ions is known as the solubility product of a salt. The solubility product constant is denoted by $K_{\text{sp}}$.
