Define:homeostasis

In the laboratory preparation of Ammonia  its written " A higher ratio by weight of the alkali used may counter act the loss by sublimation of ammonium chloride on heating in the solid state . "

Can explain the reason and if my understanding is correct .

P.S --> Its given in Viraf Dalal pg 179 if needed .
Thanks ! .
