Many of the water properties lead to some crucial physical, chemical and biochemical processes that are closely related to environmental and health problems. Some people state: (I) A relatively high dissolution of O2 in water is due largely to the dipolar property of water molecules. (II) Although the density of water changes only slightly with temperature, its change can cause lake water turnover or stratification. (III) Since water dissociation is so small (H2O ó H+ + OH-, Ka = 1.0...

In the following table, record the conductivity measured for each solution. The electrolyte type I should be strong, weak or non-electrolyte according to the table given previously. The species in solution should be a listing (in order of decreasing concentration) of the components of the solution. Ask your instructor if you need to list water as a species in solution.
