Let’s assume that during last lab you prepared a solution of NaOH. After standardization you determined the concentration to be 0.113 M. This NaOH was then used to determine the concentration of ascorbic acid in a vitamin C tablet. To do this, a Vitamin C tablet was crushed and 0.200 g were placed in a flask with 50 mL of water. The vitamin C solution was then titrated with the standard NaOH. This was repeated twice, for a total of...
