	Term	Definition
	What is the charge for Hydrogen?	+1
	How do you find the charge for an element with only a periodic table of elements?	the first row on the left of the table is +1, the second row is +2, then you skip the big section from Sc to Hg, then the next row is +3 chage, the next row is +4, the next row is -4, next is -3, next is-2, next is -1
	What is the equation used to find the solution concentration?	mass of solute divided by the mass of the solution multiplied by 100 = percent concentration
	Solubility	quantity of a substance that will dissolve in a given quantity of solvent to form a saturated solution.
	saturated	When the solvent has dissolved as much solute as it can retain stably at a given temperature.
	biodegradable	Can be broken down by living things.
	acids	Gives off Hydrogen ions when dissolved in water.
	photosynthesis	The proccess of a plant making it's own food.
	supersaturated	Solution containing a higher concentration of solute than a saturated solution at a given temperature.
	unsaturated	When you can add more of what you are dissolving to the solvent.
	neutral	in between an acid and a base
	bases	Gives off hydroxide ions when dissolved in water.
	concentration	quantity of solute dissolved in a specific quantity of solvent or solution
	Aerobic Bacteria	Need oxygen to break it down.
	Anaerobic Bacteria	Doesn't need oxygen to break it down.
	Ion Exchange	process of purifying water, which may involve the exchange of hard-water ions for other ions such as sodium.
	Regenerated	process of renewing a material; renewing used ionexchange resin by replacing hard-water ions in the resin with ions such as sodium.
	Sludge Gas	Containing both methane and carbon dioxide. It remains agter water goes through aeration and digestion.
	Bacterial Action	Conversion by bacteria of organic substances into simpler compounds.
	Hard Water	Water containing a relatively high concentration of calcium, magnesium, or ion 3 ions.
	Turbidity	The cloudiness of a solution.
	Water Treatment	Purification processes applied to water before it is distributed for consumption.
	Chlorination	The addition of chlorine to a water supply to kill harmful organisms.
	Condensation	Conversion of a substance from a gas to a liquid or solid state.
	Water Sofening	The process of removing calcium, magnesium, and ion 3 from water, results in water that readily forms a lather with soap.
	Water Sofener	Apparatus containing an ion-exchange resin; used to treat water by removing ions that cause water hardeness.
	Sewage Treatment Plant	Where the post-cleaning of municipal water occurs at.
	Evaporation	Change of a substance from a liquid to a gas.
	Filtration	Separation of solid particles from a liquid by passing the mixture through a material that retains the solid particules.
