Question

How would I find the concentration of an unknown acid if I have a Ka value of 3.98x10^-5?

Answer 1

the concentration of NaOH which is 1.0 M, pKa is 4.4, and the volume of the acid is 25 mL

Answer 2

is this ap chem?

Answer 3

no

Answer 4

ok,do u know anyone who has ap chem?

Answer 5

The Ka is the dissociation constant for the acid, write a dissociation equation and the expression (it's the same as an equilibrium expression \(K=\dfrac{products}{reactants}
\)).

You also need to know the pH of the solution, or \([H^+]\).
