The SI base unit for amount of substance is the mole. Chemistry. When one reactant is in excess, there will always be some left over. With alu­minum ni­tride. Upon adding hydrochloric acid (the simulated “stomach acid”), the mixture quickly turns red because the acid disperses throughout the beaker, first neutralizing the small amount of dissolved Mg(OH) 2, and then turning the solution acidic from the excess acid … 2) HCl(g), hydrochloric acid gas. The aqueous solution is hydrogen chloride is known as hydrochloric acid and is also called as muriatic acid. The chemical reaction between hydrochloric acid and magnesium produces magnesium chloride and hydrogen gas. Which reactant is in excess when 0.25 g of magnesium is added to 100 cm 3 of 0.1 mol l-1 hydrochloric acid (HCl)? \[Mg + 2HCl \rightarrow MgCl_{2} + H_{2}\]. The inside of the stomach is a very acidic environment, especially after food has just been eaten.
