What is the mean activity coefficient γ± of mgcl2 in an aqueous solution that is 0. 100 mol/kg in mgcl2 at 25 0c? assume complete dissociation of the salt.

A, it is falling action my have a good day

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
