Ferric chloride (FeCl₃) dissolved in water creates a yellow to brown solution. The exact shade can vary depending on the concentration of the solution.

Here's why:

* Hydration: When ferric chloride dissolves, the Fe³⁺ ions become hydrated, meaning they are surrounded by water molecules.

* Hydrolysis: In solution, some of the hydrated Fe³⁺ ions undergo hydrolysis, reacting with water to form Fe(OH)²⁺ and H⁺ ions. These reactions contribute to the color.

* Concentration: Higher concentrations of ferric chloride produce darker, more intense yellow-brown solutions.
