Homework Equations
None
The Attempt at a Solution
I just needed to clarify when it dissolves in water do...
i understand the equation but I am not sure how to determine H30 concentration and HA- Concentration with just the acid dissociation constant for hydrofluoric acid
Homework Statement
How much 4.00M of HCl is required to make 100ml of 0.400M HCl?
Homework Equations
M1V1 = M2V2
The Attempt at a Solution
Its (4.00M)*(xL) = (0.400M)(0.100L)
I think its 0.005L but the possible answer (multiple choice) say otherwise...
