Explain the equilibrium shift that occurs when water is added to the original equilibrium reaction.
Cu(H2O)62+(aq) + 4Cl–(aq) D CuCl42–(aq) + 6H2O(l)
The effect on addition of water in reaction medium can be explained by Le Chatelier's pronciple.
It says Changing any physical parmeter or concentration of reactants and products affects the equillibrium. Then the sysytem tends to neutralise the effect of this by shifting the position of equlibrium.
Here water is the product . Upon adding water to the reaction medium will increase the concentration of products and thus equllibrium will move towards left as result. (i.e. towards reactant side)
