Answers
Calamine solution is applied on the skin when an ant bites. When an ant bites, it injects formic acid into the skin. Calamine solution contains zinc carbonate which is basic in nature.
Neutral Salt: They are formed by the neutralisation of strong acids and strong bases, are called neutral salts because their aqueous solutions are neutral to litmus. Examples: The compounds like NaCl, KCl, K2S04, NaN03, KCl03, KClO4 etc are neutral salts.
A burning sensation in the stomach is usually just one symptom of an underlying condition, such as an intolerance to certain foods.
Prescription and over-the-counter medications can prevent and treat indigestion, and some home remedies can help relieve symptoms.
Anyone who regularly experiences stomach burning and similar symptoms should see a doctor. It is important to understand the underlying cause and to receive effective treatment.
