If you have a soln of HNO2 at equilibrium
HNO2 (aq) + H20 (l) <-->H3O+ (aq) + NO2- (aq)
and water is added, is there a shift in the equilibrium? Can someone explain why to me? I have a hard time understanding the concept of equilibrium and what is part of the equilibrium expression and how to determine that....thanx
