When HBr is introduced to water to generate a solution, what impact does this addition have on the pH level of the water?
HBr liberates hydrogen ions in the water, causing an elevation in the pH level.
The introduction of HBr into water results in the release of hydrogen ions, leading to a reduction in the pH level.
HBr releases hydroxide ions into the water, resulting in a decrease in the pH level.
The addition of HBr to water results in the release of hydroxide ions, thereby leading to an elevation in the pH level.
The correct answer is:
The introduction of HBr into water results in the release of hydrogen ions, leading to a reduction in the pH level.
The second option is correct: The introduction of HBr into water results in the release of hydrogen ions, leading to a reduction in the pH level.
The correct answer is: The introduction of HBr into water results in the release of hydrogen ions, leading to a reduction in the pH level.
To understand why, let's break it down:
HBr is a strong acid, meaning it ionizes completely when dissolved in water. This means that when HBr is introduced to water, it dissociates into hydrogen ions (H+) and bromide ions (Br-).
Since hydrogen ions contribute to the acidity of a solution, the addition of HBr increases the concentration of hydrogen ions in the water. This increased concentration of hydrogen ions results in a decrease in the pH level of the water.
Remember, pH is a measure of the concentration of hydrogen ions in a solution. The lower the pH value, the more acidic the solution. Therefore, the addition of HBr to water decreases the pH level.
