How much CO2 is in Alka-Seltzer?
When you place a 0.123-g tablet of Alka-seltzer in water at 27 degrees Celsius, the reaction that takes place between sodium bicarbonate and citric acid will produce 0.0248 g of carbon dioxide under your specific conditions of pressure and temperature. The volume occupied by the gas will be 16.75 mL.
Does Alka-Seltzer release CO2?
When Alka-Seltzer is dissolved in water, CO2 is released and carried to the surface by small bubbles. As bubbles reach the surface, CO2 is released into the air above the water’s surface.
Is there carbon dioxide in Alka-Seltzer?
With an Alka-Seltzer tablet, the CO2 is produced as a result of a chemical reaction. The acid mixes with the sodium bicarbonate (baking soda) to produce bubbles of carbon dioxide gas. If you look at the ingredients of Alka- Seltzer, you will find that it contains citric acid and sodium bicarbonate (baking soda).
What happens when you drop Alka-Seltzer in water?
drop the tablet in water, they mix and react, forming carbon dioxide gas which bubbles up to the surface of the water. If the water and Alka-seltzer are in a tightly sealed container, the gas will expand rapidly. These bubbles attach themselves to the blobs of colored water and cause them to float to the surface.
What is the density of carbon dioxide?

What is the limiting reactant in Alka-Seltzer?
ANSWER: sodium bicarbonate (NaHCO3) is the limiting reactant.
How does Alka-Seltzer produce CO2?
As an Alka-Seltzer tablet dissolves in water, it liberates carbon dioxide. The carbon dioxide dissolves in the water and then comes out of solution as a gas. This carbon dioxide gas has mass, but since it is a gas it escapes from the container and diffuses into the atmosphere.
What is carbon dioxide density?
Physical properties At standard temperature and pressure, the density of carbon dioxide is around 1.98 kg/m3, about 1.53 times that of air. Carbon dioxide has no liquid state at pressures below 0.51795(10) MPa (5.11177(99) atm).
What gas is produced when Alka-Seltzer and water combine?
carbon dioxide gas
Have you ever wondered why bubbles form when an Alka-Seltzer tablet is dropped into water? If you’ve ever tried it, you’ve seen that the tablet fizzes furiously. The moment the tablet starts dissolving a chemical reaction occurs that releases carbon dioxide gas.
Why does CO2 dissolve better in cold water?
The solubility of gases decreases with increasing temperature, so the air space inside the cylinder when cold water was used will be less compared to warm water. The cold water will take up more CO2 and less will be escaping to the air.
What is the density of CO2 at 27 C and 1 atm pressure?
Answer: Density of at 27° C and 1 atm pressure is 1.8 g/L.
What is the density of CO2 at 27 C and 2.5 atm pressure?
3 g L−1.
