I am assuming you are thinking of an additive to your coolant to act as a biocide. I am not exactly sure how much that you would add, but I am guessing it would be only a few mg per liter. Both compounds should be totally soluble in this scenario and certainly wouldnt affect the viscosity of the water enough to make any difference. A word of caution though. If you use AgNO3 make SURE not to use tapwater. I am pretty sure that you can test for Cl by adding AgNO3 to water. AgCl precipitates out (this compound is not all that soluble).

If you are going for addition of chemicals, why not sodium Azide? That is a much better biocide...
