To solve the problem, we need to understand the behavior of the compounds involved and the reactions that take place. Let's break it down step by step: ### Step 1: Understanding the Initial Solution The initial solution contains 1 mole of `HgI2` (mercury(II) iodide) and 2 moles of `NaI` (sodium iodide). The solution is orange in color due to the presence of `HgI2`. ### Step 2: Reaction with Excess NaI When excess `NaI` is added to the solution, a complex ion is formed. The reaction can be represented as follows: ...
