A tums tablet pulverized (powdered) and 0.4265 g of this power was mixed with 9.00 mL 1.000 M HCl. This mixture was back titrated with 0.1000 M NaOH with phenolphthalein as indicator. It required 8.25 mL of 1000 M NaOH to reach the end point. Compute % CaCO3 in the tums sample and % error.

A tums tablet pulverized (powdered) and 0.4265 g of this power was mixed with 9.00 mL 1.000 M HCl. This mixture was back titrated with 0.1000 M NaOH with phenolphthalein as indicator. It required 8.25 mL of 1000 M NaOH to reach the end point. Compute % CaCO3 in the tums sample and % error.
Expert Solution
Step 1
The formula used to calculate the percent CaCO3 is:
% CaCO3 = (mass of CaCO3/mass of Tums sample) x 100%
The formula used to calculate the moles of CaCO3 is:
moles of CaCO3 = moles of HCl/2
And the formula used to calculate the percent error is:
% error = |(experimental value - accepted value)/accepted value| x 100%
