Part 5 Flashcards
a large ion usually has the most what?
negative charge
do molecular solids have high or low melting points?
**low.. like sugar and ice- just held together by week molecular interactions. **
what is a network solid?
like a diamond, a compounds held together by an extended network of covalent bonds which are usually stronger than ionic bonds.
how is rate law calculated?
ONLY by experiment!
high Ksp value corresponds to what? (small exponent)
high solubility
low Ksp value corresponds to what? (large neg. exponent)
low solubility
the most soluble compound will have the greatest/smallest Ksp value?
greatest (small exponent)
transition metals have a tendency to form what?
complex ions
in experimental measurements, accuracy refers to what?
how close result is to actual value.
in experimental measurements, precision refers to what?
how close results are to one another (consistency)
if a solution gets colder it is..?
endothermic
solutes whose solutions are conductive are called what?
electrolytes
metals tend to form anions/cations?
cations (positive ions)
nonmetals tend to form anions/cations?
anions (negative ions)
solutes whose solutions are conductive are called what?
electrolytes
