About Chemical Balance, tick only the incorrect alternative(s), choose one or more: a) The composition of an equilibrium reaction mixture can be described by the equilibrium constant for concentration, which is equal to the concentrations of the reactants (raised to powers equal to the stoichiometric coefficients of the balanced chemical equation of the reaction) divided by the concentrations of the products (high at powers equal to their stoichiometric coefficients). b) If one of the ions coming from a salt that is already dissociated in solution is already present in solution, that salt becomes less soluble in the medium. c) The solubility product is the equilibrium constant for the solubilization reaction of an ionic solid, releasing its constituent ions into solution. In this equilibrium constant, the concentration of the solid is not omitted, as it is in its standard state. d) At the equivalence point of a precipitation titration with AgNO3, to determine the pAg+ value is independent of the original concentrations or volumes. e) After the equivalence point, in precipitation titration with AgNO3(titrant) and NaCl (titrated), we calculate the pAg+ based on the reaction with Cl-, as there is an excess of Cl- in solution.
