Why you are adding marble chips during heating?
Marble chips are added during heating so that the solution or substance can boil evenly. Evenly boiling the solution will cause it not to have heating spots, which can cause an eruption of bubbles. Heating spots are caused when the heat being applied is only getting to the liquid at the bottom of the flask, causing the liquid down there to evaporate more quickly than the upper liquid. The liquid evaporating causes bubbles to shoot through the solution vigorously, disrupting the system. To avoid these heating spots, we add marble chips or boiling chips to induce a nice, even boil.
