An evaporation dish is used in a lab to evaporate liquids, leaving behind solids that can be analyzed or collected. It is typically made of a heat-resistant material such as glass or porcelain to withstand high temperatures during the evaporation process. Evaporation dishes are commonly used in chemistry experiments to concentrate solutions or isolate solid compounds.
What else can I help you with?
Why was water left in the evaporation dish after the Bunsen burner was turned off?
Water was left in the evaporation dish after the Bunsen burner was turned off because it takes time for the water to cool down to room temperature before it fully evaporates. Additionally, some of the water may have splashed onto the sides of the dish, leading to slower evaporation.
Why water evaporate faster in a china dish as compared to test tube?
Evaporation is a process that occurs only at the surface of a liquid. If the same volume of liquid is put in a dish rather than a test tube then the liquid will have a bigger surface area allowing more room for evaporation.
Why use an evaporating dish instead of a beaker for sublimation?
An evaporating dish is better for sublimation because it has a wider surface area which allows for faster evaporation of the solid substance. This helps in obtaining the purified sublimate more efficiently. Additionally, the flat bottom of the evaporating dish ensures even heating, which is important for the sublimation process.
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 mass of evaporating dish?
The mass of an evaporating dish refers to the total weight of the dish itself. This mass is typically measured before and after the evaporation process to determine the amount of substance that has been evaporated.
What is the of evaporation dish?
an open generally shallow concave container for holding liquids for evaporation.
What kind of dish is used is in the lab to grow microscopic culture?
A Petri dish.
What term is given to the substance left in the dish when it was evaporated?
The substance left in a dish after evaporation is known as the residue.
Why is evaporation is a cooking process?
Evaporation will reduce the amount of liquid in a dish and intensify flavours. In cooking it's called reduction.
Why was water left in the evaporation dish after the Bunsen burner was turned off?
Water was left in the evaporation dish after the Bunsen burner was turned off because it takes time for the water to cool down to room temperature before it fully evaporates. Additionally, some of the water may have splashed onto the sides of the dish, leading to slower evaporation.
How many of the organisms in the lab dish are insects?

Shallow plate used in science lab?
A shallow plate which is used in a science lab is known as a petri dish.
What is the function of evaporation dish?
evaporating a solvent from a solution, leaving the solute behind.
When you put a salt water in an evaporating dish?
Salt remain as residue after evaporation.
Why water evaporate faster in a china dish as compared to test tube?
Evaporation is a process that occurs only at the surface of a liquid. If the same volume of liquid is put in a dish rather than a test tube then the liquid will have a bigger surface area allowing more room for evaporation.
What is the brand name of evaporating dish?
Many companies around the world made evaporation dishes.
Why use an evaporating dish instead of a beaker for sublimation?
