a mixture with a small amount of solute and lots of solvent

Front 6

concentrated solution

Back 6

a large amount of solute compared to solvent

Front 7

Molarity

Back 7

moles divided by liters

Front 8

stock solution

Back 8

Labs often have stock solution or really concentrate forms of things to dilute and use as need

Front 9

electrolytes

Back 9

things that when dissolved in water can conduct energy

Back 11

things that dissociate into ions when dissolved

Front 12

acids

Back 12

molecular compounds that ionized to for H+

Front 13

strong acid

Back 13

completely ionized in solution

Front 14

weak acid

Back 14

Don't completely ionize in water

Front 15

weak electrolytes

Back 15

weak acid are this

Front 16

soluble

Back 16

dissolves in water

Front 17

insoluble

Back 17

does not dissolve in water

Front 18

precipitation reaction

Back 18

when a solid forms upon mixing 2 solutions

Front 19

precipitate

Back 19

the solid in a precipitation reaction

Front 20

molecular equation

Back 20

a normal, chemical equation

Front 21

completel ionic equation

Back 21

the broken down version of all the compounds in a reaction

Front 22

spectator ions

Back 22

the parts in a precipitation that don't participate

Front 23

net ionic equation

Back 23

the simplified version of a complete ionic equation. they only show the species that change in the equation

Front 24

acid base reaction

Back 24

when an acid and base neutralize each other and produce water and a salt (when strong and strong) (weak and weak form the salt and not the water)

Front 25

Arrhenius definition

Back 25

defines an acid as a substance that produce H+ ions and a base as a substance that produce a OH- ions in an aqueous solution

Front 26

binary acid

Back 26

composed of hydrogen and a nonmetal

Front 27

oxyacids

Back 27

a hydrogen with a oxygen and nonmetal compound

Front 28

titration

Back 28

a procedure where an unknown concentration reacts with a known

Front 29

equivalent point

Back 29

the point in a titration when the moles of Oh matches the moles of H

Front 30

indicator

Back 30

the equivalent point signal (color change)

Front 31

gas evolution reaction

Back 31

a gas forms resulting in bubbling

Front 32

redox reactions

Back 32

a reaxtion where electrons are transfered

Front 33

oxidation

Back 33

loss of electrons

Front 34

reduction

Back 34

gain of electrons
