The Alka-Seltzer tablet contains citric acid and sodium bicarbonate (baking soda). When put in water, those two 'chemicals' react. The warmer the water, the faster the reaction.
The dissolution is endothermic.
The reaction of Alka-Seltzer and water is exothermic, meaning it releases heat energy. This is evident from the fizzing and bubbling that occurs when the tablet dissolves in water, which is a result of the chemical reaction between the Alka-Seltzer components and water releasing energy in the form of heat.
No, water freezing is not an endothermic reaction; it is an exothermic process. During freezing, water releases heat to its surroundings as it transitions from a liquid to a solid state. This release of energy is what causes the temperature of the surroundings to decrease. In contrast, an endothermic reaction absorbs heat from the environment.
When an Alka-Seltzer tablet is dropped into water, the citric acid and sodium bicarbonate in the tablet react to form carbon dioxide gas, which creates bubbles. This reaction is what causes the fizzing and bubbling that you see when the tablet is dropped into water.
When dissolved in water, Alka-Seltzer tablets undergo a chemical reaction that produces carbon dioxide gas, causing the tablet to fizz and dissolve. This reaction is exothermic because it releases heat energy as a byproduct, contributing to the warming sensation often experienced when using Alka-Seltzer.

yes it is a endothermic reaction
No, water freezing is not an endothermic reaction; it is an exothermic process. During freezing, water releases heat to its surroundings as it transitions from a liquid to a solid state. This release of energy is what causes the temperature of the surroundings to decrease. In contrast, an endothermic reaction absorbs heat from the environment.
Ultimately, the temperature has little effect of the reaction of water and Alka-Seltzer. However, warmer water will make the reaction occur and finish a bit faster.
(An endothermic process is one that absorbs heat.)"An endothermic reaction just took place between the water and the chemical.""Boiling water is an endothermic process that adds energy to the water molecules."
Turning water into hydrogen and oxygen is an endothermic reaction called electrolysis. An endothermic reaction only continues while energy is being added to the reactants.

It is endothermic. The heat of the water in the calorimeter decreases (giving you a -deltaH), which means that the system absorbed heat, making the reaction endothermic.
pruts
The dissolving of sodium chloride in water is an exothermic reaction because it releases energy in the form of heat.
Yes, it is true.
