a substance that acts as a reservoir for hydrogen ions donating them to the solution when their concentration falls and taking them from the solution when their concentration rises
a tautness of a sruface of a liquid, caused by the cohesion of the molecules of the liquid. water has extremely high surface tension
electrons that are the same distance from the nucleus and therefore have the same energy, even if they occupy different orbitals
the rest of the dissociated water molecule, which has retained the shared electron of the covalent bond, is negatively formed
the weight in grams that corresponds to the summed atomic masses of all the atoms in a molecule
the amount of heat that must be absorbed or lost for 1 gram of a substance to change its temperature 1 degrees C
a subatomic particle that carries no charge and is found in the nucleus of all known atoms but hydrogen
a property of the atom nuclei that refers to the affinity of the nuclei for valence electrons
when a dissociated proton is no longer counterbalanced it becomes a positively charge hydrogen ion
atoms or molecules containing an unequal number of electrons and protons and therefore carry a net positive or net negative charge
atoms with the same number of protons and electrons that are electrically neutral, having no net charge
formed when a sucrose molecule dissociates or breaks away from a crystal to prevent it from associating with other sucrose molecules. water molecules surround it in a cloud
