When an ant bites, it injects a liquid into the skin of a person which causes burning pain. A substance 'X' is added to treat the bite. Identify 'X' and tell what will be the observation when it is tested with a red litmus paper.
When an ant bites, the liquid that it injects which causes the skin to burn is Methanoic Acid.
The Substance used to treat it is a Calamine solution. Calamine solution is basic in nature and hence neutralizes the Methanoic acid.
It turns Red LItmus to Blue as it is basic in nature.
[Extra information: A neutralization reaction is when an acid and a base react to form water and a salt
It involves the combination of H+ ions and OH- ions to generate water.
When a solution is neutralized, it means that salts are formed from equal weights of acid and base.
Acid + Base → Salt + Water
Examples:
NaOH + HCl → NaCl + H2O
Mg(OH)2 + H2CO3 → MgCO3 + 2H2O
Litmus is used to test materials for acidity and basicity. This solution can also be used to differentiate between acids and bases. When acid is added to a litmus solution, it changes to red. When a base is added, it changes to blue. Neutral litmus paper is purple in colour.]
