Question

Infusing pure HCl will have what effect on H+ and pH?

A) Increase H+; increase pH
B) Increase H+; decrease pH
C) Decrease H+; decrease pH
D) Decrease H+; increase pH
E) Unchanged H+; unchanged pH

Answer 1

Infusing pure HCl into a solution will increase the concentration of hydrogen ions (H+) and consequently decrease the pH value of the solution, making it more acidic.

Step-by-step explanation:

When infusing pure HCl, it will have a significant effect on the concentration of hydrogen ions (H+) and the pH of the solution. Since HCl is a strong acid it completely dissociates in water, increasing the concentration of hydronium ions (H3O+) which are often represented simply as hydrogen ions (H+). This increase in hydrogen ion concentration will result in a decrease in the pH value.

This is because the pH scale is logarithmic and inversely related to the hydrogen ion concentration; as [H+] increases, pH decreases. Thus, infusing pure HCl into a solution will increase H+ and decrease pH which corresponds to option B).
