This solution could dissolve metal. This solution could neutralize a base. This solution would turn litmus to red. This solution has a pH of 11.20. none of the above

Regarding a 1.6 × 10⁻³ M solution of HNO₃, it is not true that this solution has a pH of 11.20.

Consider a 1.6 × 10⁻³ M solution of HNO₃. Which of the following statements is NOT true?

HNO₃ is a strong acid so that [H⁺] = 1.6 × 10⁻³ M. The pH is:

The pH < 7, as expected for an acid.

Regarding a 1.6 × 10⁻³ M solution of HNO₃, it is not true that this solution has a pH of 11.20.

This solution has a pH of 11.20

Explanation:

HNO3 is a strong acid known to ionize completely in solution. Being a strong acid, a low pH value is expected. As expected, an acid will display the following properties:

This solution could dissolve metal.

This solution could neutralize a base.

This solution would turn litmus to red.

The pH of this solution is obtained from -log[H+]

pH = -log(1.6 × 10-3)= 2.796

Hence the statement; This solution has a pH of 11.20 is not correct.

the answers would be
