The osmotic pressure of a 0.010 M aqueous solution of CaCl2 is found to be 0.674 atm at 25 oC. (a) Calculate the van\'t Hoff factor, i, for the solution. (b) How would you expect the value of i to change as the solution becomes more concentrated? Explain.
The pH of an aqueous solution at 25°C was found to be 8.30 . The pOH of this solution is . The hydronium ion concentration is M. The hydroxide ion concentration is M.
The osmotic pressure of a 0.050 M LiCl solution at 25.0°C is 2.26 atm. What is the true van\'t Hoff factor of this ionic compound? Why is it less than the ideal value?
