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?

Answer 1

When hydrogen bromide (HBr) is introduced to water, it dissociates completely into hydrogen ions (H⁺) and bromide ions (Br⁻). The dissociation reaction can be written as:

\[ \text{HBr} \rightarrow \text{H}^+ + \text{Br}^- \]

The release of H⁺ ions into the solution increases the concentration of hydrogen ions, which in turn lowers the pH of the water. Since HBr is a strong acid, it will significantly affect the pH level, making the solution acidic.

In summary, the addition of HBr to water will decrease the pH level, making the solution more acidic.
