Question

PLEASE ANSWER THE ATTACHED FILE. THANK YOU.

How many grams of calcium carbonate CaCO3 do you need in an antacid tablet to neutralize 20 ml. of stomach acid? (Stomach acid in 0.1 M HCI. There are 3.65 g of IIC1 in 1 L of stomach acid or 1 g of HC1 in 274 g of stomach acid.) Show your work. The indicator that you used in the titration was thymol blue. This indicator changes color at the end point from red (acidic) to yellow at pH 2.0. Suppose you chose phenolphthalein, which changes color at the end point from colorless (acidic) to pink at pH S3. Would you need the same, more, or less volume of NaOH in the back-titration? Explain your answer. You are a manufacturer of antacids. You could use either Mg(OH)2 or Al(OH)3 in your formulation. You can buy either of these for $2.00 per pound. Which of these will provide a better product (i.e., give more relief) for the same amount of money? Explain your answer.

Explanation / Answer

3) mass of caco3 = 0.1*20*(12+16*2+40)/2 = 84 g
