How does adding water to antimony trichloride affect (shift) the equilibrium even though it doesn't show up on the equalibrium constant expression? Is it because it dilutes the concentrations of the Cl- ions? Which way does it shift? SbCl3 (aq) + H20(l) <---> SbOCl(s) + 2H+(aq) + Cl-(aq)

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
