Question

Match the term with its description.

Answer 1

An acid is a compound that increases hydrogen ions (H+) when it is dissolved in a solution.

The term alkaline is related to compound that increases the hydroxide ions (OH−) when it is dissolved in a solution.

pH refers to a value from 0 to 14 that is used to specify how acidic or basic a compound is when it is dissolved in water

An ion is an atom or molecule that has a positive or negative charge.

Answer 2

Explanation:

Acid → A) A compound that increases hydrogen ions  when it is dissolved in a solution

Acids are those substance which gives hydrogen ions in their aqueous solutions.

Alkaline → C) A compound that increases the hydroxide when it is dissolved in a solution

Bases are those substance which gives hydroxide ions in their aqueous solutions.

pH → D) A value from 0 to 14 that is used to specify how acidic or basic a compound is when it is dissolved in water

The pH is the scale ranging from 0 to 14 used. This scale helps to determine the acidic or basic nature of a compound when dissolved in water.

Ion → B) An atom or molecule that has a positive or negative charge

Ion are those species of atom which caries positive or negative charge.

Positive charged atom = cation

Negative charged atom = anion
