Common Acids The table lists some common acids. Which element do they all have in common? .

What is an acid? An acid is a substance that produces hydrogen ions when dissolved in water. Nearly all acid molecules contain hydrogen atoms. (H) When an acid mixes with water, the hydrogen atom separates from the acid. Because of this, we also say that acids produce hydrogen ions (H+). in solution.

Common Bases The table lists some common bases. Which element(s) do they all have in common? .

What is a base? A base is a substance that produces hydroxide ions (OH-) when dissolved in water. When a base like sodium hydroxide (Na. OH) dissolves in water, hydroxide ions separate from sodium ions. This separation is called dissociation.

Dissociation is a PHYSICAL process! When acids, bases, and salts dissolve in water, their atoms are separated… https: //www. youtube. com/watch? v=EBf. Gc. TAJF 4 o but, when the water evaporates, they simply re-join. https: //www. youtube. com/watch? v=mvv. Nru. J-8 LY
