D. KOH and NaOH are both strong bases but had different effects when added to the saturated sodium chloride. Explain the equilibrium principle that accounts for these observations. E. Adding acetone to saturated NaCl solution Acetone is referred to as being completely miscible in water, meaning that it mixes with water in any concentration and there is no saturation limit. Use this information to explain the chemical principle that accounts for the observation reported above. F. What conclusions can be...
