1. An aqueous solution is made by placing 0.033 moles of Ba(IO3) in 1.000L of water (K=1.57×10-9ignoring activity) Calculate the solubility of the solution when activity coefficients are used. (Hint: determine the ionic strength)
2. What are spectator ions and how do they shift the equlibria?
Compute the change in temperature when 2 g of sodium chloride is dissolved in 270.0 mL of water initially at 25 C. The heat capacity of water is 4.184 J/mL/K. Neglect the heat capacity of the NaCl.
If [a = 2.84 (+/-) 0.02], [b = 5.02 (+/-) 0.04], [c = 21.71 (+/-) 0.06], and [d = 9.49 (+/-) 0.04], calculate the absolute uncertainty in y if y = (a+b)/(c-d).
