A solution of ammonium chloride will

📌 Concept:
-Acids have a sour taste and change the colour of blue litmus to red, whereas bases are bitter in taste and change the colour of the red litmus to blue. Litmus is a naturally occurring indicator.
-When a solution causes no change in the colour of the litmus solution, it is said to be a neutral solution. It has neither an acidic nor a basic nature.

✅ Explanation:
-Ammonium chloride is a by-product of sodium carbonate.
-It is a white crystalline salt with the chemical formula NH4Cl that is highly soluble in water.
-Ammonium chloride is formed by the neutralization reaction strong acid, hydrochloric acid, and a weak base, ammonium hydroxide.
-This indicates that the ammonium chloride is acidic. Ammonium chloride thus turns blue litmus red.
