Question

Quizplus · Accepted Answer

When HCl is added, it will react with the hydrogen fluoride present in the solution to form more fluoride ions and water. This will cause a decrease in the concentration of fluoride ion and an increase in the concentration of hydrogen fluoride. The balanced equation for the reaction is: HF + HCl → H2O + F- + Cl-
