What happens when you boil water and baking soda?

When solutes (what is being dissolved) are added to a pure liquid, its boiling temperature rises. The more solute is added, the higher it goes. The particles of the solute added interfere with the boiling of the water. The molocules cannot escape as easily in to the air, because the solutes molocules are physically blocking them. Thus the molocules have to move faster and faster to escape. The faster they go, the hotter it is. Thus the boiling point is raised.
