questions please.
1.Which graph had the steepest slope? The smallest?
2.Given the equation for the dissociation of Li, CO, below, write
the equation for the dissociation
of the ionic compounds in this lab. (Don't worry about subscripts
& superscripts) Li, CO, > 2Li+Co,2 11 12
Answer:
a) KNO, ->
b) K2S02->
c)CaCi2->
3. Since all solutions had the same concentration, what accounts
for the difference in the slope
of the three plots? Explain well.
Answer:
4. If you repeated this experiment with MgS04, would you expect the
slope of the line to be
close to that of potassium nitrate or potassium sulfate? Explain
well.
Answer:
5. In another conductiviy lab of solution, NaOH conducts
electricity but sugar does not.
Explain well. (Hint: what's different about these two molecules
chemically?)
