The substances in the list are added to water. Considering what you know about the solubility of different compounds, the types of bonds they have, their strength as electrolytes, etc., indicate which one of them will produce the solution with the HIGHEST CONCENTRATION OF IONS dissolved. NOTE: For your calculations, consider the V solution ~ V water a. 500.0 ml of water and 0.35 mol of Ca(NO3)2 O b. 500.0 ml of water and 0.25 mol of Na2SO4 O c. 100.0 ml of water and 2.0 mol of NH3 O d. 300.0 ml of water and 0.15 mol of FeCl3 O e. 100.0 ml of water and 0.7 mol NaBr O f. 500.0 ml of water and 0.7 mol of AgCI
