Prelab Activity: Titrations Continued – Titration of Household Products A 2.40 g sample of vinegar was added to an Erlenmeyer flask along with 100 mL of deionized water and 3 drops of phenolphthalein indicator. It took 22.15 mL of 0.0981 M NaOH (aq) to reach the faint pink endpoint. The following balanced chemical equation represents the chemistry of the titration: NaOH (aq) + CH3COOH (aq) à CH3COO–Na+ (aq) + H2O (l) Calculate the mass % of acetic acid (CH3COOH) in...

A portion of a crushed antacid tablet is analyzed by a back-titration. First 50.00 mL of 0.1250 M HCl is added to the tablet; then 12.51 mL of 0.1234 M NaOH is added to titrate the excess acid and reach the endpoint. Calculate the number of moles of HCl that reacted with the antacid.
A 0.450 g sample of impure CaCO3(s) is dissolved in 50.0 mL of 0.150 M HCl(aq) . The equation for the reaction is CaCO3(s)+2HCl(aq)⟶CaCl2(aq)+H2O(l)+CO2(g) The excess HCl(aq) is titrated by 9.05 mL of 0.125 M NaOH(aq) . Calculate the mass percentage of CaCO3(s) in the sample.
49.50 mL of a 2.74 M NaOH solution reacts completely with 40.44 mL of HCI solution according to the balanced chemical reaction shown below: HCI (aq) + NaOH(aq) - NaCl(aq) + H2O(1) How many moles of HCl reacted?! Please round your answer to the thousandths place. Your Answer:
A 0.450 gram sample of impure CaCO3(s) is dissolved in 50.0 mL of 0.150 M HCl(aq). The equation for the reaction is CaCO3(s) + 2HCl(aq) arrow CaCl2(aq) +H2O(l) +CO2(g) The excess HCL (aq) is titrated by 6.45 mL of 0.125 M NaOH(aq). Calculate the mass percentaageof CaCO3(s) in the sample. Please show steps.
