In this lab, i learned more about the experiment.
Yes, but the difference isn't all that great. Tablets dissolve in warm water faster than in cold water. But if you're taking an alka-seltzer, make it with COLD water. Warm alka-seltzer is especially foul tasting, and cold works as well. And it won't taste as bad.
Water. You did know that alka-seltzer dissolves in water, right?

Yes, dissolving an Alka-Seltzer tablet is considered a chemical change because the tablet's ingredients (such as citric acid and baking soda) react when coming into contact with water to produce carbon dioxide gas, which results in the fizzing effect.
Yes, water remains water even after dropping Alka Seltzer in it. The Alka Seltzer will dissolve in water, releasing bubbles of carbon dioxide gas, but the composition of the water itself does not change.
The heat gives the water molecules more kinetic energy to pull the alka seltzer particles apart (dissolve) , hence the increased temperature would speed up the rate of reaction.
The word equation for the reaction between Alka-Seltzer and water can be expressed as: Alka-Seltzer + Water → Carbon Dioxide + Sodium Citrate + Citric Acid. When Alka-Seltzer, which contains sodium bicarbonate, is added to water, it reacts to produce carbon dioxide gas, resulting in fizzing and bubbling.
Seltzer water is a liquid. Alka-Seltzer is a solid mixture.
All solutes (e.g. Alka-Seltzer) dissolve better in a warmer solvent (e.g. water).
Alka-Seltzer dissolves faster in hot water, because water is the ultimate solvent, and when water is hot, the rate of dissolving of solubility is higher.
The independent variable in an experiment involving Alka-Seltzer could be the amount of Alka-Seltzer used, the temperature of the water it's dissolved in, or the surface area of the Alka-Seltzer tablet. It is the variable that is deliberately changed or manipulated by the experimenter to observe its effect on the dependent variable.
No a seltzer has a gas phase and a liquid phase so its heterogeneous.
