Steps: 1) Get materials that are necessary to set up a Bunsen burner apparatus( ring stand, ring, wire gauze, gas burner) or use a hot plate. 2) Place a Beaker of the size that is necessary for the lab you are doing, on either the Bunsen burner or the hot plate. 3) Either light up the flame of the Bunsen Burner or turn on the hot plate and wait until the water boils. 4) If you want the hot water bath at a certain temperature in the lab you are doing, use a thermometer occasionally or hold it in to get the temperature you want. If you want the hot water bath to be as hot as it gets, just wait until the water is boiling a lot at about 100 C. Cautions and Advice in Using a Hot Hater Bath: 1) Make sure you have the beaker in the middle of the hot plate or the wire gauze, to make sure it does not have a chance of falling. It also heats the water at a faster rate. 2)Do not add too much water, it could boil over the top of the beaker. 3) Make sure when you use a thermometer either hold it in or have it hanging from a clamp. You do not want it touching the bottom of the beaker, it will not be an accurate measure. 4) Once you reach your destination of the temperature you want in the hot water bath, right away turn off either the Bunsen Burner or the hot plate and get right to the next lab step. You do not want the temperature going too high if you want it to be at an exact measurement. It could cause a source of error. 5) When taking the hot water bath from the Bunsen Burner or the hot plate, first make sure they are both turned off. You must also pick up the cylinder with a clamp so that you won’t burn yourself or drop the hot water bath. Notes: - follow these steps as you are when making a hot water bath. If followed, it is an easy task. The hot water bath is used many times throughout the labs you do in chemistry. Labs that use the hot water bath are labs when you have to heat a certain substance that you cannot heat directly above the Bunsen Burner or hot plate and when you cannot get the substance wet. It is important you do it the right way, and take caution of any danger.
