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.

∙ 7y agoThere are too many things going on in that process to characterize it as strictly chemical or strictly physical; a little of both is happening. The most visible evidence of a reaction is actually not the Alka-Seltzer (which is not a single compound) reacting with water at all, it's one component of the Alka-Seltzer reacting with another component of the Alka-Seltzer. The water is just an intermediary.
Mixing an alkali with an acid is a chemical change because it results in the formation of new substances (water and a salt) through a chemical reaction. This reaction is called neutralization.

When you add Alka seltzer to water it gives off carbon dioxide when added to water so it would be a chemical change sense their is a new chemical

Is adding milk to coffee chemical or physical?
chemical change
Is adding antifreeze to your radiator a chemical or physical change?
Adding antifreeze to your radiator is a physical change because the antifreeze retains its chemical composition and properties when mixed with the water in the radiator. It does not undergo a chemical reaction to form a new substance.
Is adding sugar to cereal a physical or chemical change?
Adding sugar to cereal is a physical change because the sugar does not undergo a chemical reaction when mixed with the cereal. The sugar retains its chemical structure and properties, only altering the taste of the cereal.
Is adding lemon to your tea a chemical or physical change?
chemical, you can't take the lemon out
Is adding calcium chloride to sodium carbonate a physical change or a chemical change?
Adding calcium chloride to sodium carbonate would be a chemical change because it results in the formation of new substances (calcium carbonate and sodium chloride) with different chemical properties than the original reactants.

Is adding water to soup A physical change or chemical change?
This is a physical process.
Is adding antifreeze to your radiator a chemical or physical change?
Adding antifreeze to your radiator is a physical change because the antifreeze retains its chemical composition and properties when mixed with the water in the radiator. It does not undergo a chemical reaction to form a new substance.
Is adding NaOH to HCL chemical or physical change?
When adding NaOH to HCl, a chemical change occurs because the two substances react to form a new compound, NaCl (table salt), and water. This is evidenced by the formation of a new substance with different properties than the original reactants.
Is addition of iron to dil . acid a physical change or chemical change?
Adding water (which is not a reactant) is a physical process.

If hydrochloric acid is added to sodium hydroxide the temperature increases but there is no visible change did a chemical or physical change occur?
A chemical change occurred. I really hope you did this experiment in a fume hood; adding a strong acid to a strong alkali usually creates a strong explosion.
Is adding food color a chemical or physical change?
yes
