Chemistry Coursework The Rate Of Reaction Between Acid and Indigestion Tablets Background Stomachs contain hydrochloric acid. It breaks down the chemicals in food. If too much is eaten some of the acid washes up into the oesophagus causing pain due to the acid corroding the lining. This is commonly known as indigestion. Indigestion tablets are bases (the opposite of acids) and so when the two substances come into contact they neutralize each other. This stops the lining of the oesophagus from being damaged and so the pain subsides. Plan There are several things that will affect the rate of reaction between the hydrochloric acid and the indigestion tablet. They are temperature, concentration, using a catalyst and changing the surface area. How the concentration of the hydrochloric acid affects the rate of reaction between it and the indigestion tablet will be investigated in this experiment. I predict that the greater the concentration of hydrochloric acid the greater...
