Ch8 Flashcards
solvent
majority liquid
solute
minority dissolved in solvent
what happens to number of moles of solute during dilution
stays the same but the volume of solvent changes
solute-solvent reactions vs solute-solute reactions
solevent solute have better reactions
Is H2O polar or nonpolar
polar
what must happen for a compound to dissolve in water
it must have dipole moments or ions
what do polar solutes dissolve in
polar solvents
what do nonpolar solutes dissolve in
nonpolar solvents
electrolyte
conducts electricity when dissolved in water
ninelectrolyte
doesn’t produce electricity when dissolved in water
why do electrolytes produce electricity
because they are composed of ions
why do non electrolytes not produce electricity
because they are composed of non ions
what forms when an electrolyte is attracted to water
ions are formed in solute
do non electrolytes have attraction to water like electrolytes
yes but they don’t form ions
strong electrolyte
decomposes into ions with full arrow showing reaction
weak electrolyte
doesn’t fully decompose into ions and has half arrow
what else should you look into when determining if something is electrolyte
if it is soluble and the arrow of the reaction
precip reaction
produces solid
what happens if no precipitate forms when two aq solutions mix
no reaction
what is double replacement
when two things just switch what they’re bonded with
oxidation
loss of electrons
oxidation agent
gets reduced causing oxidation
reduction
gaining electrons
reducing agent
gets oxidized causing reduction
