Acids are proton donors

When an acid reacts with a substance, the H+ ions bond with that substance to create a new compound. Because H+ ions are protons (see above) we can say that acids give away a proton when they react with something.

 

H+bonds with other substances meaning acids donate protons
You can remember this by seeing a pea (proton) being given as a present (given away).
