Ferric oxide (Fe2O3) is not soluble in water.
When freshly precipitated ferric hydroxide is shaken with a small amount of ferric chloride, the ferric chloride will dissolve into the solution and react with the ferric hydroxide to form additional ferric hydroxide. This process is known as peptization, where the shaking helps break down the larger particles of precipitated ferric hydroxide into smaller particles that remain suspended in the solution.
To prepare a neutral ferric chloride solution from solid ferric chloride, first dissolve the solid ferric chloride in distilled water to form a concentrated solution. Then, slowly add a base such as sodium hydroxide solution while monitoring the pH using a pH meter until the desired neutral pH is reached. Finally, dilute the solution to the desired concentration with more distilled water if needed.
To prepare a 2% solution of ferric chloride in 100ml of water, you would need to add 2 grams of ferric chloride. This is calculated by multiplying the volume of the solution (100ml) by the desired concentration (2%) and converting it to grams.
Blue litmus paper will turn red when introduced into a solution of ferric chloride. This change in color indicates that the solution is acidic.
Blue litmus paper turning red indicates that the solution of ferric chloride is acidic. This is because ferric chloride is a strong acid, which will donate protons to the water molecules, increasing the concentration of H+ ions in the solution and lowering the pH.

To prepare a ferric chloride solution, dissolve ferric chloride hexahydrate crystals in distilled water until the desired concentration is achieved. Stir the solution until the crystals completely dissolve. It is important to handle ferric chloride with care as it can cause skin and eye irritation.

Ferric alum is made by dissolving bauxite in sulfuric acid to obtain aluminum sulfate. Ferric oxide is then added to this solution to form ferric alum. The solution is then set aside for the crystals of ferric alum to form through a process called crystallization.
Ferric chloride is commonly used as an etchant for copper-based metals but is less effective on stainless steel, aluminum, and titanium. These metals are more corrosion-resistant and are not easily attacked by ferric chloride.
Blue litmus paper would turn red in ferric chloride solution due to the acidic nature of the solution, which would cause a change in the pH of the litmus paper turning it to red.
