What happens when alka seltzer is placed in water?

Answer 1

If you look at the ingredients for Alka-Seltzer, you will find that it contains citric acid and sodium bicarbonate(baking soda). When you drop the tablet in water, the acid and the baking soda react -- this produces the fizz.

Answer 2

Because there are little aliens inside each tablet that have mini ray guns and as soon as they hit water they start firing them and it makes the explosion occur. Then the little aliens drown and you drink them.

Answer 3

Alka seltzer has sodium bicarbonate (baking soda) and citric acid in its ingredients. when the alka seltzer hits the water, the baking soda and citric acid react, forming the CO2 bubbles that rise to the surface.

Answer 4

The first thing you notice dropping the tablet(s) into water is that it fizzes', this comes about by the addition of an acid and an alkali component in the tablet reacting (chemical reaction) when introduced to water, the gas (or fizz) produced is carbon dioxide.

The action of the fizz ensure good agitation for the other components to dissolve reasonable quickly so you can drink it knowing it is dissolved in the water hopefully.

Answer 5

Alka-Seltzer is a combination of aspirin (acetylsalicylic acid), sodium bicarbonate (NaHCO3), and citric acid, when the two combine it creates some carbon dioxide gas when balanced correctly.

Answer 6

It doesn't. Two components of alka-seltzer react with each other in the presence of water.

Answer 7

Plop, plop, fizz

Answer 8

The gas carbon dioxide - CO2.
