Answer:

An aqueous solution of $HNO_3$ will be an acid and have a pH of less than 7.

An aqueous solution of $NaCl$ will be a neutral solution and have a pH equal to 7.

An aqueous solution of $NaOH$ will be an base and have a pH of more than 7.

Explanation:

pH is defined as the negative logarithm of the concentration of hydrogen ions.

Thus,

pH = - log [H⁺]

pH scale generally runs from 1 to 14 where pH = 7 represents neutral medium, pH < 7 represents acidic medium and pH > 7 represents basic medium.

Thus,

An aqueous solution of $HNO_3$ will be an acid and have a pH of less than 7.

An aqueous solution of $NaCl$ will be a neutral solution and have a pH equal to 7.

An aqueous solution of $NaOH$ will be an base and have a pH of more than 7.
