Does anyone know a simple scientific experiment that I can do with hydrochloric acid?
Answer:
If you have access to any indicators, you could show the transition range of various indicators by comparing the volume of HCl needed to show a color change to the theoretical pH at which the indicator should change color. List of various indicators below:

If you have access to any organic (e.g. carboxylic) acids and NaOH, you could show how the solubility of the organic acids change with the pH of the water (most are relatively insoluble in neutral water). There are a ton of rather safe organic acids that you could use for this. Really any organic acid you could find should work for an experiment like this, but you do need to be very careful to make sure that it won't react with anything else that you're using. (This can be kinda neat to watch, something just dissolving and falling out of solution as you change the pH just slightly.)
You could show some simple reduction-oxidation reactions by dissolving metals that will not dissolve in neutral water. You could measure temperature changes and investigate how changing the amount of metal or acid changes how the temperature of the solution changes.
Hydrochloric acid is a very versatile substance and the things you can do with it are really endless, even for simple experiements. I hope that this helped to give you some good ideas anyway!
Yeah, show how HCl plus a base yields salt water. All you have to do is get any basic molecule and mix them together... Hint... make sure you use molar masses and make sure there is equal moles of each acid and base. Good luck!
