and the stoichiometric ratio given by some relevant equation, be able to solve problems like the following:
Example 4-4. 0.3527 g anhydrous sodium carbonate requires 38.47 mL HCl solution to achieve a bromocresol green end point after a procedure identical to that which you will perform in laboratory. The blank correction is found to be -0.05 mL. Determine the molarity of the acid solution.
(To be executed in class. Execution will include a discussion of the stoichiometry of the reaction, the necessity of boiling your solution just before reaching the final end point and the blank correction.)
Example 4-5. Sodium oxalate, Na2C2O4, is used as a primary standard for the standardization of potassium permanganate solution according to the equation
