Why evaporating dish is not heated directly over Bunsen burner?
Evaporating dishes are usually made of glass or porcelain which can crack or shatter when heated unevenly. Directly heating the dish over a Bunsen burner can cause temperature gradients within the dish leading to uneven heating and potential breakage. It is safer to use a hot plate or a water bath for more uniform heating.
When heating water in a beaker with a Bunsen burner what flame is required?
The flame that comes out of the Bunsen burner. it's blue/pale violet.
Can an evaporating dish be heated on a hot plate?
Yes, an evaporating dish can be heated on a hot plate to facilitate the evaporation of a solution. However, it is important to control the temperature to avoid overheating or damaging the dish. use a heat-resistant container if heating directly on the hot plate.
What is the blue flame for on a Bunsen burner?
The blue flame on a Bunsen burner indicates complete combustion of the gas fuel, typically natural gas or propane. It has a higher temperature and is used for tasks requiring high heat, such as sterilization or heating solutions in a laboratory setting.
What is a triangle of metal and pot used for in science?
A triangle of metal and pot is commonly used in scientific experiments to hold a crucible over a Bunsen burner for heating substances at high temperatures. This setup allows for precise control of the heating process and is a common technique in chemistry labs for various applications such as heating samples for chemical reactions or evaporating liquids.
A sample of copper powder is heated in an evaporating dish using a Bunsen burner. If the mass of the powder in the evaporating dish increases after heating this indicates that?
the copper must have combined with another substance.

What connects to a evaporating dish?
An evaporating dish is typically connected to a heating source like a Bunsen burner or a hot plate in a laboratory setting. This connection allows for the controlled evaporation of a liquid from the dish, leaving behind any solid residue.
Is direct heating using Bunsen burner flame advisble when evaporating the soduim cholride solution?
As long as the solution is a water-based solution, it should be fine. You should never ever use a Bunsen burner to heat a flammable liquid such as alcohol, ether, acetone, etc.
