Limestone can be considered to be essentially pure calcium carbonate. Acid rain can be considered to be sulfuric acid. When limestone buildings are croded by acid rain the reaction can be summarized by the chemical equation below. JL - 86% + 1 CaCO3() + H₂SO4 (20) → CaSO4 (aq) + CO₂(g) + H₂0 ( This reaction can be replicated in the lab by performing a titration. a. If 6.73 g of CaCO₂ solid is added to 0.5 L of 0.337 mol/L sulfuric acid, how many mols of acid will be left over after reaction? b. What volume of 2.20 mol/L KOH solution must be added to neutralize this excess acid? 6. Calculate the concentration of 25.0 mL of a sodium carbonate solution that neutralized 26.6 mL of 0.547 M hydrofluoric acid. Assume complete ionization of the acid. You must write and balance an equation for the neutralization reaction. 2KOH() + H₂SO4(x) → K₂SO4 (mg) + 2H₂00 688 109 (A BI O W 67% Fri 12:24 PM ] Tp 6 K #
