Question

The colour of ammonium chloride is:
A.Black
B.White
C.Blue
D.Green

Answer 1

Hint:We are given with the ammonium chloride. We need to find the colour of it. The chemical formula of ammonium chloride is $N{H_4}Cl$. The state of it is crystalline solid. It is highly soluble in the water.

Complete step-by-step answer:Step1. The color of the ammonium chloride is the same as the ammonium nitrate. . It is available in the laboratory. It is not available in the common market. It is available in the white powder.
Hence the colour of ammonium chloride is white. Step2. The Ammonium chloride is so highly soluble in the water. The process is an endothermic reaction. It absorbs all the heat from the surroundings. It decreases the temperature near the surroundings. It forms a little acidic solution while dissolving in the water. The time when the strong acid is mixed with the weak base makes the solution a little acidic.
Step3. When water is mixed with $N{H_4}Cl$ it breaks into the $N{H_4}^ + $ and $C{l^ - }$. It is systemic and urinary acidifying salt. It helps to maintain the pH.

So option B is the correct answer.

Note:We must not confuse the ammonium chloride with the liquor ammonia. Liquor ammonia is just an aqueous solution of ammonia. Its chemical formula is $N{H_4}OH$. While the ammonium chloride has chlorine and ammonia. The liquid ammonia is used to make drugs by the pharmaceutical companies.
