1) 0.498g sample of sodium carbonate requires 23.5 mL of a sulfuric acid solution o reach the end point for the reaction.
Na2CO3 (aq)+H2SO4(aQ)yields H2O(I)+CO2(g)+Na2SO4(aq)
Explain what is the molarity of the H2SO4?
2) A solution contains 0.063g of oxalic acid H2C2O4 *2H2O, in 250mL. Explain what is the molarity of this solution?
3) If you were given a sample of KHP contaminated with NaCl to standardize your NaOH. How would this affect the molarity calculated for your NaOH solution
