How do you make a roaring flame on the Bunsen burner?

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.
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.
What happen ton sulphar when slightly heated in test tube by a Bunsen burner?
When sulphur is heated in the test tube in the absence of air the sulphur will break down and form a red-brown liquid. If oxygen comes into play sulphur dioxide is produced, however you should not that sulphur dioxide is a highly toxic gas and should only be produced in small amounts under a fume hood.
What colour does Litmus go with phosphoric acid?
Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under acidic conditions.
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.
How do you put a test tube on a Bunsen burner?
The Bunsen burner goes under a thin, fireproof chemistry table.
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 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.
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 better to use a blue flame on a Bunsen burner?
It's hot, for one. The Bunsen burner's blue flame is unusual, however, in that it emits little light, so it can be difficult to see under some circumstances.
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 would be the difference in size of crystals between a salt solution that has been evaporated by heating with a Bunsen burner and one that was left to evaporate in normal room temperature?
When you do it on the Bunsen burner it heats quicker so you get a final product sooner. You know it's finished when you start to see white powdery looking stuff around the sides. To wash it run it under cool water and the powder should rinse out with the water.
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.
Why does a yellow flame appear on the Bunsen burner when the air hole is closed?
In a laboratory under normal conditions and with a closed oxygen valve, a Bunsen burner burns with yellow flame (also called a safety flame). This is due to the burning of very fine soot particles that are produced in the flame. With increasing oxygen supply, less black body-radiating soot is produced due to a more complete combustion and the reaction creates enough energy to producing a blue appearance flame.
