What liquids will dissolve Alka-Seltzer fastest?

What liquids will dissolve Alka-Seltzer fastest?

After the Alka- Seltzer tablet dissolved completely, the time was taken and recorded. The Alka-Seltzer tablet was dissolved in three different liquids Sprite, water, or vinegar; the results showed that the Alka-Seltzer tablet dissolved the fastest in water and the slowest in Sprite.

What factors will make an Alka-Seltzer tablet dissolve faster?

The more surface area (or exposed area) results in more sites that contact water immediately, resulting in the antacid dissolving faster and the chemical reaction (fizzing) happening faster. The crushed tablet has the smallest pieces and thus the highest surface area to volume ratio, causing it to react the fastest.

What dissolves Alka-Seltzer?

Alka Seltzer tablets easily dissolve in water. Water releases hydrogen ions that can react with the base inside the Alka Seltzer tablet, sodium bicarbonate. When the sodium bicarbonate reacts with the hydrogen ions, carbon dioxide forms, which causes the bubbles you see when you drop an Alka Seltzer tablet in water.

Does vinegar dissolve Alka-Seltzer faster?

Based on the data gathered, the less concentrated the vinegar solution is, the faster the Alka-Seltzer tablet dissolves. As the vinegar concentrated decreased, the water concentration increased. Therefore, the Alka-Seltzer tablet dissolves faster in water than vinegar.

How do you make Alka-Seltzer react faster?

Fill it with about two inches of water, add five drops of food coloring and then fill it at least three quarters full with vegetable oil before adding one quarter of an Alka-Seltzer tablet. You could repeat this activity using your homemade lava lamp at colder and warmer temperatures.

Does crushed Alka-Seltzer dissolve faster?

The crushed tablet fizzes faster than the whole tablet. That’s because it has a greater surface area to volume ratio. That means that for the same amount of antacid (one tablet), there is more surface—or exterior—to react with the water.

How much water does it take to dissolve Alka-Seltzer?

The medicines of Alka-Seltzer are in the water. Fully dissolve 2 tablets in 4 ounces of water before taking. Adults and children 12 years and over: 2 Tablets every 4 hours, or as directed by a doctor.

Does Alka-Seltzer dissolve faster in salt water?

We said Alka Seltzer will dissolve fastest in acidic water and slowest in salt water. Our data proves that the Alka seltzer tablet in the warm water dissolves the fastest (24.35 seconds). Our data also proves that the Alka seltzer tablet in the salt water dissolved the slowest (42.76 seconds).

Why does Alka-Seltzer 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.

What happens when you mix vinegar and Alka-Seltzer?

The CO2 bubbles carry some of the colorful liquid up through the oil with them, but the dense liquid quickly sinks back down to the bottom. *Vinegar reacts with the sodium bicarbonate the Alka-Seltzer, making extra carbon dioxide bubbles!

How long does crushed Alka-Seltzer take to dissolve?

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.

Why do Crushed things dissolve faster?

How is an Alka Seltzer used in an experiment?

With this particular experiment, we worked with Alka Seltzer, which is a base, or a molecule that can take up hydrogen ions. This is in contrast with an acid, which is a molecule that donates hydrogen ions. We tested the reaction rate, or the speed at which a reaction proceeds, of the Alka Seltzer at different temperatures: cold, room, and hot.

Is the Alka Seltzer name a registered trademark?

Do you need to wear safety glasses when crushing Alka Seltzer?

Repeat the experiment using sugar cubes, measuring how long the cube takes to dissolve. Wear safety glasses when crushing Alka-Seltzer. While it is a safe material, the powder can irritate your eyes. Drop the tablet into a dry cup or the reaction will start before you pour in the water.
