Calculate the molarity of an aqueous NaOH solution if 32.00ml of it is required to titrate .6789g of oxalic acid to a phenophthalein end-point. the balanced chemical equation is
H2C2O4 + 2NaOH ---> Na2C2O4 + 2H2O
I worked this for someone last night.
mols oxalic acid = grams/molar mass.
Use the coefficients in the balanced equation to convert mols H2C2O4 to mols NaOH.
M NaOH = mols NaOH/L NaOH
