Acidic solution - A solution in which the concentration of H3O+ is greater than the concentration of OH- Also, a solution in which pH is less than 7. Anions - negatively-charged ions (meaning they have more electrons than protons due to having gained one or more electrons). Arrhenius base - increases the concentration of OH- ions. Atom - An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atom...
