It is recommended to work in a ventilated laboratory hood.
Bunsen burner is not used to obtain hydrogen.
A blue cone on a Bunsen burner gives off more heat because it has a higher temperature than a yellow cone. The blue cone represents complete combustion of the gas, while the yellow cone indicates incomplete combustion with lower temperature.
Robert Bunsen added an air hole to it so it could have oxygen as well as gas. when the air hole is open the flame you get is blue and is hotter than when the air hole is closed, which then gives a yellow flame.
Boric Acid! When boron is heated, electrons absorb a certain amount of heat energy that causes them to jump to higher energy levels. After While, these electrons lose their energy and fall back down to their original levels, and as they do so, they emit energy in the form of light. Because the energy absorbed by electrons is different per element, each element will give a different color. Boron gives off a green color.
An acidic solution would have a sour taste and turn litmus red. Acids release hydrogen ions when dissolved in water, which gives them these characteristics.

Air hole fully open gives a 'roaring blue flame'
Because it starves it of oxygen, without oxygen the combustion is not as efficient. When the sides of the bunsen burner are open it draws air into the tube like a venturi and makes the combustion of the gas more efficient.i hope that my answer has helped you :)
The blue flame is the hottest... The yellow one is called a safety flame and if you swipe your hand qckly through the safety flame, it won't burn... If you do it quick enough
Yes, in a basic solution, there are more hydroxide (OH-) ions than hydrogen (H+) ions. This is what gives a basic solution its higher pH value compared to an acidic solution.
When acids in water hydrogen positive ion is produced in excess. It is this hydrogen positive ion that gives acidity of a solution.
yes they do and bases release hydroxide ions

burner usually gives off blue flame because it receives enough oxygen to keep it burning at full strength. but after passing through wire gauze the flame turns red because it then receives a disrupted, less and unsteady amount of oxygen. this also causes the temperature of the flame to fall.
An acid is a substance that releases hydrogen ions, H+, in an aqueous (water) solution, or a substance that gives up a hydrogen ion to another molecule or ion depending on which definition you use.
