Document Summary

The number of moles of the solute in a volume of a solution of known molarity can be obtained by multiplying together the known molarity and solution volume in liters. Example: how many ml of 0. 250 m hg(no3)2 solution will react with 25. 0 ml of 0. 200 m. 25. 0 ml nacl x 0. 200 m x 1 mole hg(no3)2 x 1000ml = 10. 0ml. Some solutes called electrolytes produce water solutions that conduct electricity well. Some solutes called nonelectrolytes produce water solutions that do not conduct electricity. Strong electrolytes form solutions that conduct electricity because they dissociate completely into charged ions when they dissolve. An example of a strong electrolyte is nacl. Weak electrolytes form weakly conducting solutions because they dissociate into ions only slightly when they dissolve. An example of a weak electrolyte is acidic acid. Nonelectrolytes form nonconducting solutions because they do not dissociate into ions at all when they dissolve.
