Question 4 At 70°C, the solubility of Y2S3 is 5.6 x 10-14 M. What is this compound's Ksp at 70°C? Question 5 At 40°C, the Ksp of Hg(BrO3)2 is 1.3 x 10-7. What is this compound's solublity in Mat 40°C? Question 6 points (Extra Credit) Save Artswe Calculate the concentration of Cd2+ at equilbrium after 122.0 mL of 0.0174 M Cd(NO3)2 and 256.0 mL of 0.363 M KCN are combined. The Ksp of Cd(CN)2 (s) is 8.9 x 10-8.
