Acids and bases in water. When an acid is poured into water, it gives up H (hydrogen) to the water. When a base is poured into water, it gives up OH (hydroxide) to the water. Stronger acids give up more protons (the positively charged parts of atoms); stronger bases give up more OH-(hydroxide).
Neutral substances have an even balance of protons and OH
