Part 10 Flashcards
true or false: NH4 is ionic even though it lacks a metal
TRUE
in what type of solution do acid-base reactions and redox reactions occur?
ionic solution
do metals tend to form cations or anions?
cations
do nonmetals tend to form cations or anions?
anions
when is a solute considered a strong electrolyte?
when it dissociates completely into its constituent ions
ex: NaCl, KI and compounds with highly polar covalent bonds
what are nonelectrolytes?
compounds that do not ionize at all in aq solution
ex: nonpolar gases & organic compounds (oxygen & sugar)
weak electrolytes only ionizes slightly in aq soltuion. what are some examples?
acetic acid (and other weak acids) ammonia (and other weak bases) & HgCl2
weak acids & weak bases
what formula is used when asked a dilution problem?
m1v1 = m2v2
only true equation when same number of each molecule in both compounds! for instance 2 H’s before and after..otherwise use N1V1=N2V2 …with normality!
