Unformatted text preview: diluted acid. The stoichiometric point was reached after 26.50 mL of acid had been added. a) Write the balanced equation for the reaction of HCl(aq) with Na 2 CO 3 (aq). b) What is the molarity of the original hydrochloric acid? 3. A vitamin C tablet was analyzed to determine whether it did in fact contain, as the manufacturer claimed, 1.0 g of the vitamin. A tablet was dissolved in water to form a 100.0 mL solution, and a 10.0-mL sample was titrated with iodine (as potassium triodide). It required 10.1 mL of 0.0521 M I 3-to reach the stoichiometric point in the titration. Given that 1 mol I 3-2245 1 mol vitamin C in the reaction, is the manufacturers claim correct? The molar mass of vitamin C is 176 g.mol-1 . 1...
