Questions LWhy is it necessary to equalize the pressure (i.e., have the water level the same in each tube) before taking a volume reading? 2 Why is it important to use water that has been pre-saturated with CO: in the gas burettes? 3If your antacid sample had been contaminated by moisture, what effect (if any) would you expect this to have on your result? 4 Students should write their results for antacid composition of both your first and second sample on the laboratory board. This will enable you to judge the reproducibility of results. If you were given an unknown sample, would you be able to identify it as either Hor Q? Explain. NOT APPLICABLE FOR CHMO01 (Lab Online). 5List three potential sources of error in this experiment. 6 Explain why an 'antacid" is called as such (Hint: refer to the balanced equations you wrote on page 2 of this report sheet, what is the role of the NaHCO or CaCO in these reactions?) Z Describe, in your own words, what the overall aim of this experiment was, and how the measurements and calculations you performed were used to achieve this aim. 3-5 sentences

Questions 1.Why is it necessary to equalize the pressure (i.e., have the water level the same in each tube) before taking a volume reading? 2_Why is it important to use water that has been pre-saturated with CO: in the gas burettes? 3_ If your antacid sample had been contaminated by moisture, what effect (if any) would you expect this to have on your result? 4. Students should write their results for antacid composition of both your first and second sample on the laboratory board. This will enable you to judge the reproducibility of results. If you were given an unknown sample, would you be able to identify it as either H or Q? Explain. NOT APPLICABLE FOR CHM001 (Lab Online). 5. List three potential sources of error in this experiment. 6 Explain why an 'antacid' is called as such (Hint: refer to the balanced equations you wrote on page 2 of this report sheet, what is the role of the NaHCO or CaCOs in these reactions?) 7. Describe, in your own words, what the overall aim of this experiment was, and how the measurements and calculations you performed were used to achieve this aim. 3-5 sentences
