Words and meanings to learn
hypothesis
a prediction or proposed explanation made at the start of an investigation, based on prior knowledge or scientific understanding, that can be tested by conducting an experiment
electrodes
conductors, usually made of a metal or carbon, that allow current to pass into and out of an electrolyte during electrolysis
aqueous solution
a solution in which water is the solvent; substances dissolved in water are shown with the state symbol (aq)
electrolysis
