Answer:
The correct answer is option 4.
Explanation:
Substance which releases hydroxide ions([tex]OH^-[/tex]) in an aqueous solution are termed as bases.
Substance which releases proton ([tex]H^+[/tex]) in an aqueous solution are termed as acids.
From the given options:
[tex]CH_3COOH[/tex] : It is an weak organic acid known as acetic acid. Being acid it releases [tex][H&+][/tex] ion in an aqueous solution.
[tex]CH_3COOH(aq)\rightarrow CH_3COO^-(aq)+H^+(aq)[/tex]
[tex]CH_3COH[/tex] : It is an alcohol named methanol and it is slightly acidic.They gives [tex]H^+[/tex] ions and alkoxiode ions.
[tex]CH_3COH(aq)\rightarrow CH_3CO^-(aq)+H^+(aq)[/tex]
[tex]HCl[/tex] : It is strong acid known as hydrochloric acid. Being highly acidic it releases [tex][H&+][/tex] ion in an aqueous solution.
[tex]CH_3COOH(aq)\rightarrow Cl^-(aq)+H^+(aq)[/tex]
[tex]KOH[/tex] : It is strong base known as potassium hydroxide. Being highly acidic it releases [tex][H&+][/tex] ion in an aqueous solution.
[tex]KOH(aq)\rightarrow K^+(aq)+OH^-(aq)[/tex]
CH3COOH is a compound that release hydroxide ions in a aqueous solution.
Compound refer to a substance that comprises of two or more elements that are chemically bonded together. They can be covalently bonded or ionically bonded. CH3COOH is a weak acid that dissociate into hydroxide ion when it is dissolve or react with water.
Therefore, CH3COOH is a compound that release hydroxide ions in a aqueous solution.
