What evidence of a chemical reaction might you see in dropping an alka-seltzer tablet into water?
Chemical, bubbles of gas are fromed, it fizzes. --> Yes that is a chemical change that occurs, but the dissolving of the tablet is considered a physical change, therefore a physical and a chemical change occurs when water and an alka-seltzer tablet combine,
Is the reaction of Alka-Seltzer and water endothermic or exothermic?
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.
Is water still water after dropping Alka seltzer in it?
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.
Is an Akkad seltzer tablet fizzing physical or chemical?
The fizzing of an Alka-Seltzer tablet is primarily a physical change. When the tablet dissolves in water, it releases carbon dioxide gas through a reaction between citric acid and sodium bicarbonate. This gas formation produces bubbles, which is the observable fizzing. However, since a chemical reaction occurs during this process, it can also be considered a chemical change.
What variable must controlled to provide evidence to support the law of conservation of mass when alka-seltzer and water are mixed?
When Alka-Seltzer and water come into contact it creates a reaction that produces gas. This is evident by the fizzing bubbles. In order to support the law of conservation of mass you would need to capture and measure the gas.
What evidence of a chemical reaction might you see dropping an alka-seltzer tablet into a glass of water?
You might observe fizzing or bubbling as the tablet dissolves in the water due to the release of carbon dioxide gas. This effervescent reaction is evidence of a chemical reaction occurring between the ingredients in the tablet and water.

Is aka-Seltzer dissolving in water a physical or chemical change?
It is not only a dissolution but also a chemical reaction; consequently a chemical change.
Is the reaction of Alka-Seltzer and water endothermic or exothermic?
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.
Is adding alkali to acid a chemical or physical change?
This is a chemical change, because the carbon dioxide is created from the ingredients when placed in solution. The effervescence is caused when citric acid and sodium bicarbonate combine to form sodium citrate, releasing carbon dioxide gas.
How are the results of seltzer tablets relate to the rate of a chemical reaction?
By the formation of gas,that helps with stomach aches and gas.
Is water still water after dropping Alka seltzer in it?
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.
Why is a lava lamp with Ala seltzer a physical change?
Adding Alka-Seltzer to a lava lamp causes a physical change because it does not alter the chemical makeup of the substances, only the appearance and behavior. The fizzing and bubbles are a result of a physical reaction caused by the release of gas, rather than a chemical reaction.
What is the reaction of sprite with alka-seltzer?
When Sprite, a carbonated beverage, is mixed with Alka-Seltzer, a medication containing citric acid and sodium bicarbonate, a chemical reaction occurs. The citric acid in the Alka-Seltzer reacts with the sodium bicarbonate to produce carbon dioxide gas. This gas is released as bubbles, causing the Sprite to fizz and bubble up rapidly. This reaction is similar to the fizzing that occurs when Alka-Seltzer is dissolved in water, but the carbonation in the Sprite enhances the effect.
IS alka-seltzer gives off carbon dixide when added to water a chemical?
Yes, when Alka-Seltzer tablets are added to water, they undergo a chemical reaction that produces carbon dioxide gas. This reaction occurs because the citric acid and baking soda in the tablets react to produce carbon dioxide gas, which creates the fizzing effect.
What happens when alka-seltzer and iodine are mixed?
When Alka-Seltzer and iodine are mixed, the Alka-Seltzer tablet will react with the iodine, causing it to fizz and release carbon dioxide gas. This reaction does not have any significant chemical significance beyond the physical reaction of gas formation.
Is an Akkad seltzer tablet fizzing physical or chemical?
The fizzing of an Alka-Seltzer tablet is primarily a physical change. When the tablet dissolves in water, it releases carbon dioxide gas through a reaction between citric acid and sodium bicarbonate. This gas formation produces bubbles, which is the observable fizzing. However, since a chemical reaction occurs during this process, it can also be considered a chemical change.
