Question

When $NO$ is passed into $KOH$ solution, products are:
A. ${{N}_{2}}$
B. ${{H}_{2}}O$
C. Both A and B
D. None of these

Answer 1

$KOH$ is known by the name potassium hydroxide which is an inorganic compound and the common name for this compound is caustic potash. It is known as base where we know that base are those compounds which are bitter in taste and have the presence of hydroxyl group in them.

Complete answer:
Potassium hydroxide is known as prototypical strong base like sodium hydroxide which is represented by the chemical formula $NaOH$, it has many industrial applications and has more reactivity towards acids. Where acids are generally those substances which are capable of donating a proton i.e. hydrogen atom to another substance while bases are those substances which are able to accept a hydrogen ion from an acid.
$NO$ is known by the name nitric oxide or nitrogen monoxide; it is one of the principal oxides of nitrogen. Nitric oxide is a free radical which represents that it has no unpaired electrons. It can also be known as a heteronuclear diatomic molecule. Nitric oxide is used as an important intermediate in many organic reactions.
When $NO$ is passed into $KOH$ solution two main products are formed: nitrogen gas and water.

This suggests that option B is the correct answer.

Note:
An oxide is a chemical compound which contains at least one oxygen atom with any other element. Oxide is a di anion of oxygen represented as ${{O}^{2-}}$ . In this state the oxygen is present in -2 oxidation state and acts as an anion which carries a negative charge.
