We have learned in this chapter that many ionic solids dissolve in water as strong electrolytes, that is, as separated ions in solution. What properties of water facilitate this process? Would you expect ionic compounds to be soluble in elemental liquids like bromine or mercury, just as they are in water? Explain.
calculate the freezing point of a nonionizing antifreeze solution containing 388 g ethylene glycol, C2H6O2 and 409 g of water.
Since water does absorb CO2 from the atmosphere and since CO2 dissolved in water causes it to be slightly acidic, will the use of deionized water that has not been previously boiled cause the mass of acetic acid in the vinegar to be calculated as ..
