From the amount of NaOH added at the 1st equivalence point, calculate the original molarity of the acid. Carry out the same calculation based on the amount of NaOH added at the 2nd equivalence point. Label all parts of your work clearly.

Molarity of acid, Ca = Cb*Vb*A/Va*B

Explanation:

Using H2SO4 as acid, the reaction is as follow:

2NaOH  +  H2SO4 ⇒ Na2SO4  +  2H2O

Volume of acid = Va; Volume of base = Vb, Molar concentration of  acid = Ca; Molar concentration of base = Cb; Molarity of acid = A and Molarity of base = B

Ca*Va/Cb*Vb =A/B

∴ Ca = Cb*Vb*A/Va*B

catya that's not even a b or c
