Research: The Alka Seltzer tablets are little round antacid tablets that are made of sodium bicarbonate, potassium bicarbonate, and citric acid those are what makes the Alka Seltzer Tablet dissolve. (Science Project) When the Alka Seltzer Tablet is dropped into hot water, the tablet dissolves faster because the atoms move faster in the hot temperatures. If the Alka Seltzer Tablet is dropped into cold water the atoms would not move as fast as the hot water atoms because the atoms are going to slow. (Moyer ,Richard) When the Alka Seltzer Tablet is dissolving in a liquid it also depends on the room temperature either if it’s high or low. If the Alka Seltzer Tablet is dissolving in a soda the tablet will dissolve fast because the soda also has atoms that move fast because the soda has gas in it (Background Information) If the Alka Seltzer Tablet is dropped in Salt water the tablet will dissolve fast but not too fast because the atoms are not moving that fast. (Moyer, Richard) The best temperature for that a Alka Seltzer tablet to dissolve is room temperatures. When the tablet is dropped into different liquids, it causes rapid disintegration. The Alk Seltzer tablets is made for when someone has astomach pain and they drink the Alka Seltzer tablet when it’s already dissolved and then the pain goes away. When an acid makes contact with a base in this case (alcati) they produce energy; in the case of the Alka Seltzer, the acid is the A. Citric and the base is the carbonate of sodium. These two components are in the salt form, there is not asubstance that does not permit a reaction, that why it needs water to start a reaction, after this basically the bicarbonate of sodium release Dioxide of Carbon (CO2), this releases as a gas and makes bubbles. (Background Information) The Bicarbonate discompose and lose that CO2, precipitates like a salt, if you leave the Alka Seltzer in the cup for a couple of minutes you will see in the bottom white substances and that is salt. (Background Information )

The Alka Seltzer Tablets contains baking soda which makes it dissolve. When solid dry powders acid are pressed together to make a tablet, being solids the molecules are mobile enough to react. When water connects with the tablet the tablet begin to dissolve. (background information).

What I learned I learned that the Alka Seltzer Tablet is part made of baking soda which makes the tablets dissolve when it connects with the water. = Works Cited =
