        [Systematic] Contributing factors that cannot be implemented into the stomach may affect the results in comparison to theoretical data (factors such as foods that one may eat, temperatures, mucus on stomach, etc.)

        Limitations
        
        This experiment can only test antacids that primarily work by neutralizing acid; antacids that provide a protective layer or cause the body to react accordingly cannot be tested as they do not apply to acid.
- - - - Prepare capsules by filling approximately one capsule half with preferred powder (Calcium carbonate, Magnesium hydroxide, Sodium bicarbonate, sodium carbonate, Aluminium Hydroxide)
        
        Finish building the capsule by putting the top on while gloved
        
        Pour 25 ml of Hydrochloric Acid into a beaker
        
        The acid provided has a molarity of 0.1. Dilute the Acid by adding 5ml of water to make sure that the molarity is 0.02
        
        Add 3 drops of universal indicator into the acid - it should turn into an orange/red color
        
        Add appropriate bases into a capsule.
        
        Drop capsule into the beaker with hydrochloric acid
        
        Begin a timer
        
        Reaction takes place and the color of the liquid in the beaker changes
        
        Once the color is green, the reaction will be complete and the timer should be stopped (green is the pH of 7 and is neutral)
        
        Note down the time taken for the neutralization reaction to take effect.
        
        Repeat for other antacids.
        
        Once all the results have been collected, determine the antacid that took the least amount of time to take place - this is the most effective antacid.
