The model below shows a molecule. The model is H - Br with 2 dots on top of the Br and after the Br and at the bottom of the Br so I total are 6 dots. When HBr is introduced to water to generate a solution, what impact does this addition have on the pH level of the water?

A. HBr liberates hydrogen ions(H+) in the water, causing an elevation in the pH level.
B. HBr releases hydroxide ions (OH-) into the water, resulting in a decrease in the pH level.
C. The introduction of HBr into water results in the release of hydrogen ions (H+), leading to a reduction in the pH level.
D. The addition of HBr to water results in the release of hydroxide ions (OH-) , thereby leading to an elevation in the pH level.

The correct answer is:

C. The introduction of HBr into water results in the release of hydrogen ions (H+), leading to a reduction in the pH level.

HBr is a strong acid, and when it dissociates in water, it releases hydrogen ions (H+), which increases the acidity of the solution and consequently lowers the pH level.
