How Do You Make A Replica Of Stomach Acid?
Learning what’s in the human body makes a great science project for any K-12 student. One way to find out more about how the body works: replicate some conditions outside of it. Stomach acid, the active component of which is hydrochloric acid, digests our food. Make a replica of stomach acid with materials available from chemistry supply or hardware stores, and learn the power of the environment in the human stomach by testing the simulated stomach acid on food or antacid tablets. Replicating Stomach Acid for a Science Project Step 1 Assemble supplies, with adult help if necessary. Hydrochloric acid, the active component of stomach acid, can burn the skin. Ask a science teacher for a sample of 0.1 M hydrochloric acid (M, short for molarity, is a measure of the quantity of molecules of a chemical in solution.) This concentration simulates the strength of stomach acid. Step 2 Seek out “muriatic acid” at a hardware store if you cannot get a standardized solution from a science teacher. Ha
