Question

Ammonium hydroxide is found in:
(A) Lime water
(B) Window cleaner
(C) Soap
(D) Milk of magnesia

Answer 1

Hint: Ammonium hydroxide is the aqueous solution and is formed by saturating the solvent i.e. water with gaseous ammonia.
- Ammonia evaporates easily.

Complete step by step answer:
- So in the question, it is asked that ammonium hydroxide is found in which of the compounds given below. So first let’s talk about the compound ammonium hydroxide. The question asked here is completely a factual type of question. Here we have to discuss some facts about the compound ammonium hydroxide which will give us the answer. The answer for the above given question is all about the chemical properties of the compound, ammonium hydroxide.
- So let’s discuss some of the facts about ammonium hydroxide ($\text{N}{{\text{H}}_{\text{4}}}\text{OH}$).
- Ammonium hydroxide is the aqueous solution of ammonia and is also called as ammonia water etc. The ammonium hydroxide is also represented as $\text{N}{{\text{H}}_{\text{3}}}_{\left( \text{aq} \right)}$.
- The ammonium hydroxide is a colorless solution and is a weak base. It does not ionize completely leaving the water molecule and this solution is used as a buffer solution i.e. a solution which is used to adjust the $\text{pH}$ in a chemical reaction. Since the solution concentration of $\text{O}{{\text{H}}^{\text{-}}}$ ions increases , thereby an increase in the basicity of the solution.
- The ammonium hydroxide is a powerful reagent and it has the tendency to breakdown the stains that are caused by the vegetable fats, animal fats etc. Hence the compound is a good cleaning agent and is an easily vaporizing compound and because of this property it is used in the detergents that are used for cleaning glass, windows etc.
- So finally by comparing the options given we could say that ammonium hydroxide is used in window cleaner. The correct option is option “B” .

Note: Lime water is the solution of calcium hydroxide.
The soap is the compound which is made up of sodium salt of fatty acids for example, sodium stearate.
- The milk of magnesia is the solution of magnesium hydroxide.
