1. Write the balanced chemical equation for the reaction of KHP with NaOH. 2. Suppose your laboratory instructor inadvertently gave you a sample of KHP contaminated with NaCl to use in standardizing your NaOH. How would this affect the molarity you calculated for your calculated for your NaOH solution? Justify your answer. 3. How many grams of NaOH are needed to prepare 200 mL of 0.300 M NaOH? 4. 4 A solution of malonic acid, H2C3H204, was standardized by titration with 0.1000 M NaOH solution. If 20.76 mL of the NaOH solution is required to neutralize completely 12.95 mL of the malonic acid solution, what is the molarity of the malonic acid solution? H2C3H204 + 2 NaOH → Na2C3H204 + 2 H2O 5. Sodium carbonate is a reagent that may be used to standardize acids in the same way you used KHP in this experiment. In such a standardization, it was found that a 0.512 g sample of sodium carbonate required 26.30 mL of a sulfuric acid solution to reach the end point for the reaction. Na2CO3 (aq) + H2SO4 (aq) → H20 (1) + CO2(g) + Na2SO4(aq) What is the molarity of the H2SO4? 6. A solution contains 6.30 x 10-2g of oxalic acid, H2C204.2 H20, in 250 ml. What is the molarity of this solution?
