What type of reaction is Alka-Seltzer?
Gas-Forming Reactions Carbonates like Alka Seltzer, when mixed with an acid, will always form a salt and carbonic acid. Because carbonic acid is so unstable, it will rapidly break down into water and carbon dioxide; this reaction is a decomposition reaction.
When an antacid tablet dissolves in water the fizz is due to a reaction between sodium hydrogen?
the fizz is due to a reaction between sodium hydrogen. carbonate (NaHCO3), also called sodium bicarbonate, and citric acid (H3C6H5O7)
What is the formula of the substance that causes the fizz when the antacid dissolves in water?
Write down the FORMULA of the substance that causes the fizz when the antacid dissolves in water. A certain antacid contains 1,8 g of H3C6H5O7 and 3,36 g of NaHCO3. The antacid is dissolved in 100 cm3 distilled water in a beaker….QUESTION 1: MULTIPLE-CHOICE QUESTIONS.
| COMPOUND | FORMULA | BOILING POINT (°C) |

What is the reaction between Alka-Seltzer and water?
Alka-Seltzer and other fizzing tablets produce carbon dioxide-filled bubbles when placed in water. As the carbon dioxide is produced, you can see bubbles grow and float to the surface of the water.
Why do antacids dissolve in water?
When an antacid tablet dissolves in water, the fizz is due to a reaction between sodium hydrogen carbonate and citric acid.
What type of reaction is an antacid?
Antacids work by counteracting (neutralising) the acid in your stomach. They do this because the chemicals in antacids are bases (alkalis) which are the opposite of acids. A reaction between an acid and base is called neutralisation.
When do antacid tablets dissolve in water?
These antacid tablets fizz when they come in contact with water because of a chemical reaction. The water reacts with the tablet to create bubbles full of carbon dioxide gas. Chemistry has a lot to do with chemical reactions, but it also studies properties of materials.
What is the mole ratio between CO2 and NaHCO3?
You will measure the ratio of moles NaHCO3 used to moles of CO2 produced, and if it is approximately 1:2, you may conclude that Reaction A is correct; if the ratio is around 1:1, you can bet that Reaction B is correct, and if it’s about 2:1, you should choose Reaction C.
Which mineral is used in antacids?
Calcium and magnesium are naturally occurring minerals that are necessary for many systems in the body. Calcium is necessary for bone formation and maintenance. Calcium carbonate and magnesium hydroxide is a combination antacid used to treat indigestion, upset stomach, and heartburn.
Why does Alka-Seltzer fizz in water?
As the tablets dissolve, the sodium bicarbonate splits apart to form sodium and bicarbonate ions. The bicarbonate ions react with hydrogen ions from the citric acid to form carbon dioxide gas (and water). This is how the bubbles are made.
What happens when antacid tablets reacting in water?
These antacid tablets fizz when they come in contact with water because of a chemical reaction. The water reacts with the tablet to create bubbles full of carbon dioxide gas. Since the water can reach more of the tablet immediately, the reaction, or fizzing, happens faster.
Why does antacid tablets dissolve?
Effervescent antacid tablets contain an acid, similar to vinegar or lemon juice, and a base, similar to baking soda. When the acid and base are dry like they are in the tablet, they do not react. When they dissolve in the water, they react to produce carbon dioxide gas.
