Ammonia is added to solutions of cobalt, nickel, and copper 2+ cations. First formation of the hydroxide precipitate is seen, then of the ammonia complex. Pour 0.1M solutions of Cu2+, Co2+, and Ni2+ ...

Therefore, if the temperature is increased, the equilibrium position moves in the endothermic direction (to the left) to reduce the temperature. This means that less ammonia (NH 3) will be produced.

The addition of NH4Cl to a solution of ammonia shows the effect of adding a common ion to a system at equilibrium. Add water to each of two beakers. Add 2 drops of phenolphthalein to each. Add a few ...
