Need help with:
1) Calculate the moles of H+neutralized by the antacid per tablet and the moles H+neutralized per gram of the antacid tablet.
2) Calculate the average mass of the antacid tablets.
3)Calculate the mass of the active ingredient per tablet in your antacid based upon your titration data.
4)Calculate a percent error based on the mass of the active ingredient per tablet measured through titration relative to what was found on the label.
Here is the data collected from the lab:
Active Ingredients: Calcium Carbonate 500mg (Antacid )
DATA:
Trial 1:
Mass of antacid 1= 1.3027g
Molarity of HCI solution=0.105M
Volume of HCI solution=125.0 mL in each flask
Molarity of NaOH solution=0.0885M
Initial buret reading1 =0.00mL NaOH
Final Buret reading 1= 44.68mL NaOH
Trial 2:
Mass of antacid 2= 1.3068 g
Molarity of HCI solution=0.105M
Volume of HCI solution=125.0 mL in each flask
Molarity of NaOH solution=0.0885M
Initial buret reading1 =0.10mL NaOH
Final Buret reading 1= 41.43 mL NaOH
