Question

1. 500 mL of a 6 M solution of HCl is diluted by the addition of water. The concentration of the HCl is now?

2. Which of the following is a weak acid (weak electrolyte)?: HBr, HI, H2SO4, HNO3, or HF (please explain your answer)

Answer 1

Answer #1

1) answer = concentration of HCl will decrease.

if we dilute solution by adding water the solution becomes dilute.

if we know howmuch water added we can calculate final concentration also.

2) HF is weak acid

HF dissociates partially in aqueous solution so it is weak acid.

Answer 2
