Answer #1

Crushing the tablet would allow only reaction to takes place faster because crushing or pulverizing will increase the surface area of particles. But pulverizing wouldn’t change the amount of antacid in that tablet. Hence antacid content from tablet will surely react with HCL under all conditions only reaction speed will be affected because of the surface area available for the reaction will different. Pulverization will only affect the size of the particle and not the content of the sample.

An analysis of generic antacid tablets labeled to contain 750 mg of CaCO3 (MM= 100.09 g/mol) per tablet of active ingredient was performed. The analysis was performed by dissolving a 0.985 g sample of the antacid tablet in 90.00 mL of 0.175 M HCl. The excess acid was back-titrated with exactly 33.15 mL of 0.155 M NaOH. The average weight of a tablet is 1.025 g. The tablet came from a bottle of 175 tablets that cost $4.99. Calculate the...

Analogy to the Vinegar Analysis We analyze a vitamin C tablet for ascorbic acid, a weak acid with a molar mass of 176.13 g/mole. Once crushed and dissolved in water, it titrates to a nice phenolphthalein/peach-colored endpoint in a 1:1 reaction with sodium hydroxide. A single tablet of 0.607 g is titrated to endpoint against 0.1120 M sodium hydroxide solution. The initial volume of sodium hydroxide titrant is 0.34 mL, and at endpoint the volume is 26.38 mL. Use this...

Below is the background info for the lab assignment. The 4 blank boxes are the questions I would like answers too. The end point for the fine titration was 35.90 mL in the burette when the solution turned bright green again. And the coarse titration I got 35.36mL as the end point. 35.9 mL is exact in case you need that info. Thanks!
