unit 5 Flashcards
why’s is oxidation? loss or gain
loss of electrons
what is reduction?
gain of electrons
what is exothermic
releasing energy
what is endothermic
absorbing energy
what is a reaction rate
the rate at which reactants change into products over time
what are the factors that affect reaction rates
temperature, surface area, concentration, stirring, catalysts
what is concentration
number of particles in a given volume
what are catalysts
substance that affects the reaction without being used up in the reaction speeds it up
what is the solute
salt
what is the solvent
water
what are the three ways substances can dissolve in water by
dissociation dispersion and ionization
what is dissociation
the process in which ionic compounds separates into ions as it dissolves
what is an ionic compound
neutral overall but made of ionic elements
what is dispersion
breaking into small pieces that spread throughout the water
physical properties of a solution
conductivity freezing point and boiling point
what is an acid
a compound that produces hydronium ions
properties of acids
sour reactive with metals produce color change with indicators
properties of bases
bitter taste slippery feel color changes on indicator
what does the neutralization reaction between and acid and base for
salt and water
what is salt
an ionic compound

lose donate
do bases lose or accept protons
accept
what are proton donors
acids
what are proton acceptors
bases
