|
A substance that, in water, seperates into electrically charged particles.
|
Electrolyte
|
|
|
Seperate; break down. For example, sodium bicarbonate, when placed in water, dissociates into sodium cation and a bicarbonate anion.
|
Dissociate
|
|
|
A charged particle; an atom or group of atoms whose electrical charge has changed from neutral to positive or negative by losing or gaining one or more electrons. (In an atom's normal, nonionized state, its positively charged protons and negatively charged electrons balance each other so that the atom's charge is neutral.)
|
Ion
|
|
|
An ion with a positive charge - so called because it will be attracted to a cathode, or negative pole.
|
Cation
|
|
|
An ion with a negative charge - so called because it will be attracted to an anode, or positive pole.
|
Anion
|
|
|
A substance that tends to preserve or restore a normal acid-base balance by increasing or decreasing the concentration of hydrogen ions.
|
Buffer
|
|
|
The difference in concentration between solutions on opposite sides of a semipermeable membrane.
|
Osmotic Gradient
|
|
|
The movement of molecules through a membrane from an area of greater concentration to an area of lesser concentration.
|
Diffusion
|
|
|
The passage of a solvent such as water through a membrane.
|
Osmosis
|
|
|
The concentration of solute per kilogram of water.
|
Osmolality
|
