Homework Answers
NiCO3 + HCl 
NiCl2 + CO2 + H2O
Due to odd ion effect the equilibrium will shift in the forward direction hence we can say that sopubility will increases
Option b is correct :- Solubility will increases

Question 4 07 1.5 pts What is the concentration of Pb2+ in a saturated solution of PbCl2 in 0.10 M KCl solution. (Ksp = 1.4 x 108)? Why is [Pb2') in this question (smaller/larger) than in Question 3? Hint: What is the initial [CI] before PbCl2 is dissolved? because the presence of chloride ion prevents the dissolution 1.4 x 10M of PbCl2 1.5 x 10M same as in Question 3 1.4 x 10-M, because the presence of chloride ion slows...

5. (36 pts total) To determine the molar solubility and solubility product constant of magnesium carbonate, Matt stirred 5 g of MgCO3 powder in 150 mL of 0.0041 M MgCl2 solution for 15 minutes. After waiting an additional 10 minutes, he separated the undissolved solid by filtration and collected the filtrate in a dry Erlenmeyer flask. He determined the concentration of CO2 in the filtrate to be 1.40 x 10M Answer the following questions based on Matt's experimental data. For...
