Question

HELP PLEASE!

When phenol dissolves in water, a few (no all) of the molecules ionize H+ from the -OH group. This makes it
O a reducing agent
O an oxidizing agent
O a weak acid
a weak base

Answer 1

Answer: a weak acid

Step-by-step explanation:

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases. Oxidizing agent is the substance which itself gets reduced by gaining electrons and thus oxidize others.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced. Reducing agent is the substance which itself gets oxidized by losing electrons and thus reduces others.

Weak acids are those substances which dissociate partially to give
`H^+` ions when dissolved in water.

`C_6H_5OH\rightleftharpoons C_6H_5O^-+H^+`

Weak bases are those substances which dissociate partially to give
`OH^-` ions when dissolved in water.

`NH_4OH\rightleftharpoons NH_4^++OH^-`
