The independent variable in an experiment involving Alka-Seltzer could be the amount of Alka-Seltzer used, the temperature of the water it's dissolved in, or the surface area of the Alka-Seltzer tablet. It is the variable that is deliberately changed or manipulated by the experimenter to observe its effect on the dependent variable.
There are 325 mg of aspirin in one tablet of the original alka-seltzer. There is a modern version called alka-seltzer gold that contains no aspirin.
