Calcium Carbonate in Antacid: Why Higher Yield in Wet Flask?

  • Thread starter lmlgrey
  • Start date
In summary, when determining the concentration of calcium carbonate in an antacid tablet, using a wet flask will result in a significantly higher concentration due to the reaction between HCl and calcium carbonate. The method involves calculating the difference in moles of gas before and after the reaction, and the pressure sensor measures the partial pressure of CO2 in the flask.

1. When determining the concentration of calcium carbonate in an antacid tablet, why using a wet flask will end up with a significant higher concentration?



2. Gas laws



I would expect a lower yeild of gas since some of the calcium carbonate reacts with water and escape from the tube...but higher??

Can you describe the method that you are using? It's hard to answer without knowing how you determine the concentration of calcium carbonate.
 
  • #3
A reaction happened between HCl and antacid (which contains calcium carbonate) and the reaction flask was equipped with a pressure detector... by calculating the difference between # of moles of gas in the flask before and after(nf-ni=(pf'/Tf-pi'/Ti)*V/R...
 
  • #4
Your pressure sensor measures the pressure of every gas within the flask. It is more proper to say that you are measuring the partial pressure of CO2. What other gases are present in the flask?
 

FAQ: Calcium Carbonate in Antacid: Why Higher Yield in Wet Flask?

1. What is calcium carbonate and why is it used in antacids?

Calcium carbonate is a chemical compound that is commonly found in rocks, shells, and pearls. In antacids, it serves as an active ingredient that helps neutralize excess stomach acid and relieve symptoms of heartburn and indigestion.

2. What is the difference between a wet flask and a dry flask when testing calcium carbonate in antacids?

A wet flask contains a small amount of water, while a dry flask does not. When testing calcium carbonate in antacids, a wet flask allows for better mixing and dissolution of the antacid, resulting in a higher yield of calcium carbonate.

3. How does calcium carbonate in antacids neutralize stomach acid?

Calcium carbonate reacts with stomach acid (hydrochloric acid) to form calcium chloride, carbon dioxide, and water. This reaction helps to neutralize the acid and reduce the burning sensation in the stomach.

4. What other factors can affect the yield of calcium carbonate in antacids?

The type and concentration of acid in the stomach, the type and amount of antacid used, and the temperature and mixing of the solution can all impact the yield of calcium carbonate in antacids.

5. Is calcium carbonate safe to consume in antacids?

Yes, calcium carbonate is generally considered safe to consume in antacids. However, it is important to follow the recommended dosage and consult a healthcare professional if you have any underlying health conditions or are taking other medications.
