What happens to the antacid tablet when added to vinegar?

What happens to the antacid tablet when added to vinegar?

Vinegar is an acid called acetic acid. When it combines with calcium carbonate in eggshell and in the antacid tablet, a chemical reaction takes place. In the reaction, the atoms in the acetic acid and the calcium carbonate come apart and rearrange in different ways to make new chemicals.

What is vinegar and how does it influence chemical reactions?

Vinegar is a solution of acetic acid in water. Acetic acid reacts with sodium bicarbonate to produce carbon dioxide, just as the citric acid in an effervescent tablet does.

How was the method of adding increasing amounts of vinegar to the tablet used to determine limiting reactant?

When NaHCO3 is in excess, the acid (H+) in the reaction is the limiting reactant. As the amount of vinegar is increased, more sodium bicarbonate will react and more CO2 will be produced. On the other hand, when the acid is in excess, sodium bicarbonate becomes the limiting reactant.

Why does antacid dissolve faster in hot water than in vinegar?

Does an antacid tablet dissolve faster in hot or cold water? (Answer: Hot; it has more energy to react with the antacid.) These faster moving warm water molecules find and react with antacid molecules much quicker than cold water molecules.)

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.

What happened to the crushed antacid after it was added in the water?

Effervescent antacid tablets are made from aspirin, citric acid and sodium bicarbonate. When sodium bicarbonate dissolves in water, it reacts with hydrogen ions from the citric acid and forms carbon dioxide. Because carbon dioxide is a gas, it forms bubbles inside the water that you can see as foam on the surface.

How does the temperature of vinegar affect the rate of reaction?

When you increase the temperature, which is the average speed of the molecules, the quicker speed makes it more likely for them to bump into each other. Therefore, the reaction is quicker due to the increase in collisions. The colder vinegar should not produce more carbon dioxide.

What happens when vinegar is mixed with water?

Vinegar is a polar substance, and its molecules are attracted to water molecules (called “hydrophilic”). Therefore, it is able to be mixed with water. It does not technically dissolve; rather, it forms a homogenous solution with water.

Why was vinegar added to the reaction?

Why was vinegar added to the reaction? A. The acid reacts with the bicarbonate ions to generate water and carbon dioxide gas.

Why does Alka-Seltzer react with vinegar?

How does it work? Alka-Seltzer reacts with an acid to make carbon dioxide gas. When you added the tablet to the vinegar or water, you heard fizzing and saw bubbling. If the reaction is going faster, then it will take less time to finish and will fizz more vigorously.

Why does antacid dissolve faster in hot water?

In the hot water, the tablet should have more vigorously produced bubbles than in the cold water. The higher the temperature, the faster the molecules move, and the more likely it is that the bicarbonate will contact hydrogen in just the right way for the chemical reaction to occur and produce carbon dioxide bubbles.

How does temperature affect the rate of reaction?

An increase in temperature causes a rise in the energy levels of the molecules involved in the reaction, so the rate of the reaction increases. Similarly, the rate of reaction will decrease with a decrease in temperature.

How long does it take a tablet to dissolve in cold water?

After the tablet was added to the ice-cold water it should have taken much longer to dissolve, with most of the tablet disappearing after about two to three minutes, but with some bubbles still apparent after six minutes or longer. In the hot water the tablet should have more vigorously produced bubbles than in the cold water.

What happens when soda is added to water?

Hypothesis: If soda is added to the water and tablet, then the dissolving rate will be longer because more substances were mixed to the solution/mixture.

How are carbon dioxide tablets dissolved in water?

The tablets also include other ingredients, such as citric acid (a weak acid that adds flavor—as well as provides important hydrogen ions, which will come into play as you shall soon see). To take the tablets, they’re fully dissolved in water, where they famously undergo a chemical reaction that produces lots of carbon dioxide bubbles—or fizz.

How long does it take Alka Seltzer to dissolve in hot water?

After the Alka-Seltzer tablet was added to the hot water the tablet should have quickly dissolved, taking some 20 to 30 seconds to do so, depending on the exact temperature.
