Question 8 Incorrect Mark 0.00 out of 1.00 For the reaction: PbCl₂(s) Pb2+ (aq)+2C1¹ (aq), what is Q when 6.0 mL of 0.078 M lead nitrate is added to 14 mL of 0.027 M sodium chloride? Ksp of lead chloride is 1.6 x 10-5 M³. Hint given in general feedback *Recall: Q is compared to Ksp to determine whether a precipitate forms. Answer: 2.34E-2 x Remember each solution is diluted by the other solution.
Sodium phosphate is added to a solution that contains 0.0094 M aluminum nitrate and 0.025 M calcium chloride. The concentration of the first ion to precipitate (either Al³* or Ca²+) decreases as its precipitate forms. What is the concentration of this ion when the second ion begins to precipitate? Answer: 8.66E-10 X Note that well over 99% of the first ion has precipitated before the second ion starts to precipitate. Finish review
