Question

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

1.
oxidation
2.
reduction
3
hydrolysis
4.
neutralization

Answer 1

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

Step-by-step 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.
