The Correct Option is C

Solution and Explanation

Step 1: Understand milk of magnesia.
Milk of magnesia is a colloidal suspension of \[ Mg(OH)_2 \] in water.
It behaves as an antacid and is commonly used to neutralize excess hydrochloric acid present in the stomach.

Step 2: Write the neutralization reaction.
The excess stomach acid reacts with magnesium hydroxide as: \[ Mg(OH)_2+2HCl \rightarrow MgCl_2+2H_2O \] This reduces acidity and relieves stomach disorders such as acidity and indigestion.

Step 3: Analyze other options.

Silver sol: Mainly used for its antiseptic properties.

Antimony sol: Not used for stomach disorders.

Gold sol: Mainly used in medicinal and research applications, not as an antacid.
Hence, milk of magnesia is the correct choice.

Step 4: Final conclusion.
Therefore, the colloidal solution used to treat stomach disorders is \[ \boxed{\text{Milk of magnesia}} \]
