How do you imitate hydrochloric acid in a science project?

Answer 1

You can try using ethanoic acid (vinegar) instead. It is much safer and more easily obtainable, although is is a weaker acid. But the characteristic vinegar smell is likely to give you away so if you are performing a close up project then it is not recommended.

Another alternative is to use citric acid. Aqueous citric acid looks like hydrochloric acid (both colourless) and does not have that smell. You can buy that in baking shops.

Answer 2

To imitate hydrochloric acid in a science project, you can create a solution of vinegar (acetic acid) and table salt (sodium chloride). When mixed together, the acetic acid reacts with the sodium chloride to produce a solution that imitates the properties of hydrochloric acid, such as its acidic nature and ability to react with certain metals. Remember to exercise caution and follow safety guidelines when working with acids.
