Hydrobromic acid is a strong acid. If you have 1 L of a 7.5 M solution of Hydrbromic acid?
A) What is the concentration of H_3O^+?
B) What is the PH of this solution?
C) If you dilute 1 liter of 7.5M in HBR solution to a volume of 2 L what is the new concentration?

1) HBr, being a strong acid, ionizes 100%; therefore, (H^+) = 7.5 <
2) pH = -log(H3O^+)
3) mL x M = mL x M
