Which type of flame is good for heating in Bunsen burner?
A Bunsen Burner has an air hole at the base of the burner tube. When closed', the flame is bright yellow and slick. The flame is 'cool'. The yellow colur are white hot particles of carbon. When 'open,' the flame is pale blue and roaring. The flame is 'hot'. The pale blue colour is carbon dioxide being formed from atmospheric oxygen.
How long does it take for a porcelain to turn red in a Bunsen burner?
Porcelain will not turn red when subjected to a Bunsen burner flame. Instead, it will remain white and may heat up without significant visible change.
What type of flame is used for heating in Bunsen burner?
A Bunsen Burner has an air hole at the base of the burner tube. When this air hole is closed, the flame is yellow, slack, relatively cool, and will deposit carbon (soot ' black powder). NB THe yellow colour are white hot particiles of carbon. When the air hole is open ame is pale blue, roaring, of definite shape, relatively hot, and does not deposit any carbon. NB The pale blue flame is carbon paricles being comverted to carbon dioxide. Its use in a modern lab. is very limited, because you cannot 'fine' control the temperature, in the manner of an electric mantle, which has a temperature control.
When you heat copper sulphate with Bunsen burner?
Heating copper sulfate with a Bunsen burner will cause the compound to undergo a dehydration reaction, where it loses water molecules to form anhydrous copper sulfate. The characteristic blue color of the copper sulfate will change as it loses water molecules and turns white.
What are the two types of the gas burner flame?
Yellow, smoky flame: indicates incomplete combustion due to insufficient air supply, resulting in inefficient burning and soot formation. Blue, clean flame: indicates complete combustion with optimal air-fuel ratio, resulting in efficient burning and minimal emissions.

What happens when air hole in Bunsen burner is half open?
A hot flame is obtained (but not the hottest) with a color violet-white.
Is the blue flame of a Bunsen the hottest?
no the white flame is the hottest
What color should the Bunsen burner flame be?
The ideal Bunsen burner flame should be blue. A blue flame indicates complete combustion of gas and is the hottest part of the flame. Adjust the air and gas flow until a steady blue flame is achieved.

What colour is barium chloride?
for the most part you really can't tell if it's coloring the flame at all, that is if you're burning it right on a Bunsen burner. if you're lucky it might spark or give the slightest bit of a white flame.
When magnesium ribbon is bought near the Bunsen flame it catches fire and the colour of the flame produced would be?
The flame is white and very luminous.
How is ice used over a Bunsen burner?
Well, isn't that a happy little question! Ice is used over a Bunsen burner to cool down a reaction or a substance that has become too hot. By placing the ice above the Bunsen burner, the heat energy is absorbed by the ice, causing it to melt and keeping the area around the burner cool. Just like adding a touch of white to a painting to create contrast, using ice over a Bunsen burner helps balance the temperature and keep things running smoothly.
How do you adjust the Bunsen burner so that only colored light is observed?
I think you mean "get rid off the white smokey flame". Open the air aperture at the bottom to admit more oxygen usually by turning a small collar.
What is the scientific name of laboratory glass plate?
The little white one? It's called an evaporating dish that you put your items and water in and let it evaporate over the Bunsen burner.
