... An experiment was carried out to determine the percentage of calcium carbonate in eggshells. Step 1: A mass of 0.620 g eggshells was crushed and added to 25.00 mL of 0.300 mol L 1 HCl and allowed to react until there until no more bubbles were evolved. Some HCl did not react and remained in the rea ...
