Which chemical formula represents hydrochloric acid?

Explanation:
Understanding chemical formulas of acids helps you identify which formula matches which substance. Hydrochloric acid is a simple compound made of hydrogen and chlorine in a 1:1 ratio, so its formula is HCl. In other words, one hydrogen atom pairs with one chlorine atom to form the molecule. When dissolved in water, HCl forms hydronium and chloride ions, but the molecular formula remains HCl, which is why this option uniquely represents hydrochloric acid. For context, H2O is water, H2SO4 is sulfuric acid, and NH3 is ammonia (a base), so they do not correspond to hydrochloric acid.
