Positively charged hydrogen ions are attracted to the lone pair of electrons of the water molecules. In acid-base theory, the concentration of hydrogen ions is considered, but the actual concentration of hydrogen ions in solution is very _______ . In practice, the hydrogen ion and hydronium ion are functionally _______ .

Draggable item		Corresponding Item
heterogeneous		any substance that dissolves to form free ions, which make the solution electrically conductive.
electrolyte		the amount of a dissolved substance per unit volume of a solution
precipitate		a solution containing a small amount of solute relative to the amount solvent
solvent		to add a solid material to a liquid in such a way that its particles completely disperse into the liquid, usually becoming invisible within the liquid
homogeneous		made up of two or more distinct components; usually refers to a mixture in which individual substances are distinct
dissolve		made up of one uniform component; often used to describe a mixture with a consistent composition and a single phase throughout
solution		solid particles that have been separated from a solution
solute		the substance that is dissolved in another substance
concentration		a homogeneous mixture of two substances that appear as only one state of matter
dilute solution		the substance that dissolves another substance
