What happens to pottery under a blue flame on a Bunsen burner?
Applying a blue flame from a Bunsen burner to pottery can potentially cause the pottery to crack or break due to the rapid temperature change. The intense heat from the flame can also cause the pottery to discolor or change in texture. It is important to heat pottery slowly and evenly to avoid these issues.
How do you make a roaring flame on the Bunsen burner?
To get a roaring (blue) flame you simply turn the sleeve on the Bunsen burner's chimney to completely open the air hole under it. The new blue flame will be hard to see so close the air hole afterwards to make a visible flame.
Can you heat a beaker over a Bunsen burner?
YES!!! If it is a normal chemistry lab. beaker. Method; Set up a tripod. Put a gauze mesh across the top of the tripod. Set the beaker on the gauze mesh. Under the gauze mesh and between the legs of the tripod, place a Bunsen Burner. Ignite the Bunsen Burner with the airhole SHUT. (Cool bright yellow flame). Allow the flame to gently warm the gauze mesh and beaker. When moderately warm, you can then open the airhole for a roaring hote pale blue flame). This will then heat the contents of the beaker. NB DO NEITHER hold the beaker in your hands, NOR in tongs, over an open flame ; burns.
Why can you not use the yellow flame on a Bunsen burner to heat things?
You can, it would just take much much longer. It turns out that the blue flame is the hottest because it contains more oxygen. The reason being that with more oxygen, it has more energy to create heat. The hottest part of the blue flame is actually right under the middle, this part is called the crown.
How do you made nickel sulphate?
1. Tie hair up, put lab coat on and put goggles on. 2. Get a 50cm3 beaker and measure 25cm3 of sulphuric acid 3. Measure 3 grams of the nickel carbonate on the weighing scale and add it to the sulphuric acid. 4. Stir continuously with a glass rod until the reaction is complete and no color change is occurring. 5. Get a conical flask with a funnel and filter paper and filter the solution which was made. 6. When filtration is complete add solution to a beaker and heat under the safety flame of a Bunsen burner 7. After 2/3 of the solution has evaporated stop the Bunsen burner and leave solution. 8. Wait a week and crystals are formed with the name nickel sulphate.
How do you put a test tube on a Bunsen burner?
The Bunsen burner goes under a thin, fireproof chemistry table.
What is the mat called that's placed under a Bunsen burner?
The mat that is placed under a Bunsen burner can be referred to as a heat proof mat.
Why should you never put lighted Bunsen burner under a shelf?
because the fire will burn up the shelf.
What happens when you are trying to separate salt water and you place it in the oven without putting it under the Bunsen burner first?
Splashing may occur.
Should you always put a gauze mat under a Bunsen burner?
Asbestos does not burn and insulates. If the Bunsen burner should tip over or the material being heated by the burner should drop, the asbestos will protect the tabel underneath. Certain forms of asbestos have been found to be ealth hazards so now most often other minerals are used in the insulating mats in laboratories.
What is a beacker and how is it used?
A beaker is basically a glass cup with numbers on the side.It is used to measure water with. You might use it to heat water under a Bunsen Burner.
Why is it important that you should tie your hair back when using a Bunsen burner?
It is important to pull your hair back when using a Bunsen burner to prevent it from coming into contact with the open flame and igniting your hair.You are instructed to pull back your hair when using a Bunsen burner to prevent your hair from coming into contact with the open flame and catching your hair aflame.

Why is it better to use a blue flame on a Bunsen burner?
It is better to use a blue flame on a Bunsen burner because it indicates complete combustion of the gas, resulting in a hotter and more efficient flame for heating or sterilizing purposes. A blue flame also produces less soot and smoke compared to a yellow or orange flame.

How would you get pure water from salty water?
You will need: 2 beakers(1 named A and 1 named B) Salty water A stand A Bunsen burner A CLEAN aluminum tray 1.Put the salty water in beaker A. 2.Put the stand and the Bunsen burner under it. 3.Put beaker B and shape next to it. 4.Hold the clean aluminum tray above it diagonally. 5.Turn the Bunsen burner on. 6.Wait for the salty water to evaporate and form water droplets which will fall into the beaker B. And you will get pure water unless the aluminum tray is dirty. -------- - distillation - ion exchange - reverse osmosis etc.
