- The value of Keq for the reaction shown below is 1.08 x 10-10. If 5 g of BaSO4 is added to a 100 mL beaker of water, what would the concentration of barium ions be in the resulting solution once it reaches equilibrium? Hint: BaSO4 will dissociate into equal moles of Ba2+ and SO42-, meaning that [Ba2+] will equal [SO42-] at equilibrium.
BaSO4 (s) ⇌ Ba2+ (aq) + SO42- (aq)
hint: answer 1.04x10^-5 M

4.81 mL of 0.00200 M Fe(NO3)3, 2.85 mL of 0.00200 M KSCN and 2.34 mL of distilled water were mixed. The resulting solution was allowed to attain equilibrium at 24 oC. The absorbance of the equilibrium solution was recorded, and the [FeSCN2+] was determined graphically to be 7.58 x 10-5 M. Part A: Calculate the number of moles of Fe3+ initially added to the solution. Part B: Calculate the number of moles of FeSCN2+ formed in the solution at equilibrium....
