Answer 1

Weak acid ------ option B

Step-by-step explanation

Acid is divided in strong and weak acid

Generally, acid can be defined as a substance that will produce hydrogen ions as the only positive ions when dissolved in water.

Strong acid will dissolved completely in water to give hydrogen ions. Example of a strong acid is Hydrogen

Weak acid will dissolved partially in water to give hydrogen ions

Hence, a compound that will give only few of its molecules to produce hydrogen ions when dissolved in water is called a weak acid

Therefore, the correct answer is weak acid
