Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out 28.mg of oxalic acid h2c2o4 , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250.ml of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used 28.4ml of sodium hydroxide solution. calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
