Answer:
The right answer is: d. Q> Ksp A precipitate will form.
Please see the calculations and explanation below
For Mg(OH)2, Ksp = 6x 10-12 What will occur if 1.0 L of 0.010 M Mg(NO3),...
Will a precipitate form when 100.0 mL of 6.8 x 10-4 M Mg(NO3)2 is added to 100.0 mL of 1.2 x 10-4 M NaOH? The ion product for Mg(OH)2 is 1. Since Q is than Ksp, Mg(OH)2 precipitate from the solution.
The Ksp of AgCl at 25 °C is 1.6 x 10-10. Consider a solution that is 1.0 x 10-2 M in CaCl2 and 1.0 x 10-8 M in AgNO3. A. Q> Ksp and a precipitate will form. B.Q> Ksp and a precipitate will not form. OC.Q<Ksp and a precipitate will not form. D.Q<Ksp and a precipitate will form. E. The solution is saturated.
Will a precipitate form if the pH of a 0.015 M solution of Ni(NO3)2 is adjusted to 9.00? Ksp Ni(OH)2 = 1.7 x10-6 .
3. (4 marks) Will a precipitate form if the pH of a 0.015 M solution of Ni(NO3)2 is adjusted to 9.00? Ksp Ni(OH)2 = 1.7 x106
please answer both questions
QUESTION 24 To 1.0 L of water, 3,0 x 10 mol of Pb(NO3)2, 4.0 x 10 mol of K2C+04, and 1.0 mol of NaCl are added. What will happen? Disregard the increase in volume due to added substances. Salt Esp PbC+04 1.8 * 10-14 PbCl2 16 x 10-5 A precipitate of PbCrO4 will form. b. A precipitate of KCI will form. No precipitate will form. A precipitate of PbCl2 will form QUESTION 25 What is the...

above what Fe2+ concentration will Fe(OH)2 precipitate from a
buffer solution that has a pH of 8.42? the Ksp of Fe(OH)2 is
4.87x10^-17
Question 28 of 31 > Attempt 6 - Above what Fe2+ concentration will Fe(OH), precipitate from a buffer solution that has a pH of 8.42? The Kp of Fe(OH), is 4.87x10-17 [Fe2+1 = 1.95 x10-11
2. A solution is 0.10M in Mg(NO3)2. a. What concentration of OH is required to just start precipitation of Mg(OH)2? (Ksp = 1.5x10-11) b. If NH3/NH4+ buffer is used to control the pH, and [NH3] = 0.10 M, what concentration of NH4 is required to prevent the precipitation of Mg(OH)2?
What is the molar solubility of Mg(OH)2 in a basic solution with a pH of 12.00? Ksp for Mg(OH)2 is 5.6 × 10-12.
Consider the reaction: Mg(OH)2 (s) = Mg(aq) + 2 OH- (aq) At equilibrium, a 1.0 L reaction vessel contains 5.3 moles of Mg(OH)2 and concentrations of 0.0080 M and 0.010 M of Mg and OH respectively. What is Kc for this equilibrium? Consider the reaction: N2 (g) + 3 Br(g) = 2 NBr) (g) At equilibrium, the concentrations of Nz and Bra are 0.34 M and 0.70 M respectively, and the concentration of NBrs is 0.090 M. What is Kc...
