Question 2 (1 point) An aqueous solution of Zn(OH)2 is in equilibrium according to the reaction below. Suppose Zn(NO3)2 is added to the solution, and it is allowed to come to a new equilibrium. What will happen to the pH as a result of addition of Zn(NO3)2? The pH increases. The pH is unaffected by the addition of Zn(NO3)2. The pH decreases.
Question 3 (1 point) Will a precipitate form (yes or no) when 6.0x10-4 M AgNO3 is added to 1.0x10- 4 M Na₂SO4? If so, identify the precipitate. The Ksp for Ag2SO4 is 1.5x10-5. Assume no dilution occurs. Yes, the precipitate is Na₂SO4 Yes, the precipitate is AgNO3 Yes, the precipitate is Ag2SO4 OYes, the precipitate is NaNO3 No, a precipitate will not form
