Name Cassandra Turner ANALYSIS OF AN ANTACID, PART III 1. A common antacid is calcium carbonate. Write the equation for the reaction of calcium carbonate solid with aqueous hydrochloric acid (as would occur in your stomach!) CaCO3 (s) + 2HCl(aq) → CaCl₂ (aq) + CO₂(g) + H₂O(l) III. Pre-Lab II. Your calcium carbonate antacid tablet weighed 1.50 g. You added 25.00 mL of a 1.00 M solution of HCl. Then you titrated the excess HCI with 0.100 M NaOH. It took 14.33 mL to the endpoint. SHOW WORK! 25.00mL IL Tiocom 0.0250 L HCI How many moles of HCI did you add initially? 0.0250 moles. 1. moi 00 x 0.0250L = 0.0250 moles L How many moles of NaOH did you use in the titration? 0.001433 moles 0.100 mo mox 0.014 33L = 0.0014 33 moles How many moles of HCI were titrated (left over)? 0.001433 moles HCI 0.001433 mol NaOH Imol HCl = 0.001433moles.
