At 298k, the solubility product of agbr in water is 7.7x 10^-13. first, 5g o AgBr is added to 100 g of water to reach equilibrium at 298 K (a=0.509 at 298K) 1) pleases calculate the concentration of Ag+ in the solution 2) if 5g of Na2So4, salt is added into the same solution and reach a new equilibrium. calculate the new concentration of Ag+ in the solution. My professor said we have to use "I" in question 2 but im confused on that part
