When aqueous KI is added gradually to mercury(II) nitrate, an orange precipitate forms. Continued addition of KI causes the precipitate to dissolve. Write balanced equations to explain these observations. (Hint: Hg2+ reacts with I to form HgI42−.)

Interpretation Introduction

Interpretation:

It is given that, when aqueous KI is added gradually to mercury (II) nitrate, an orange precipitate is formed and a continued addition of KI causes the precipitate to dissolve. The balanced equations are to be stated to explain these observations.

Concept introduction:

The formation of solid in a solution is known as precipitation.

Explanation of Solution

Explanation

To write: The balanced equations to explain the given observations.

Addition of aqueous KI to mercury (II) nitrate leads to formation of an orange precipitate HgI2 . When KI is further added continuously, a soluble HgI42 ion is formed
