Question

Which reaction occurs when equivalent quantities of H" (or H30) and OH" are mixed?

Answer 1

Answer: A reaction which occurs when equivalent quantities of H" (or $H_{3}O^{+}$) and OH" are mixed is a neutralization reaction.

Explanation:

When acid and base chemically combine together to form sat and water then it is know as neutralization reaction.

An acidic substance gives hydrogen ions $(H^{+})$ on dissociation and a basic substance gives hydroxide ions $(OH^{-})$ on dissociation.

For example, $H^{+} + OH^{-} \rightarrow H_{2}O$ is a neutralization reaction where an acid and base are mixed together to form water.

No salt is formed as because here the reactants are not present as compounds.

In a hydrolysis reaction, water molecule(s) is added to the reactant molecules.

For example, $CH_{3}COOCH_{3} + H_2O \rightarrow CH_{3}COOH + CH_{3}OH$

Oxidation is the process of addition of oxygen to a molecule and removal of hydrogen.

Reduction is the process of addition of hydrogen in a compound and the removal of oxygen atom.

Therefore, we can conclude that reaction which occurs when equivalent quantities of H" (or $H_{3}O^{+}$) and OH" are mixed is a neutralization reaction.
