What is the term given to the solid left after evaporation?
ashes
Does salt water effect is evaporation?
no. because salt is left as it is in the base during evaporation.
What is the process when evaporation occurs and the minerals are left behind in solid state eventually forming the strata?
Solidification
What is the principle of using evaporation as a separation technique?
during evaporation a substance that is dissolved in the liquid is left back and the liquid goes into air. So evaporation is used as a seperation technique.
Can you separate a soluble from a liquid?
A soluble substance can be separated from a liquid by evaporation. Evaporate off the liquid and the solid is left behind.
what other method of separating a liquid from a solid did you learn today other than filtration?
Methods of separating a solid and liquid rather than filtration. (a)When a solid and liquid are soluble,a method know as evaporation is used.When this mixture is heated,the liquid will evaporate and the solid will be left and obtained after evaporation. (b)When the mixture is insoluble,it is separated by use of decantation.The mixture is given some time to settle and the liquid is poured into another beaker and the the solid is left in the initial beaker.
Why aren't clouds salty?
Clouds are formed due to the large scale evaporation of the earth's water. During the evaporation process the salt is left behind.
When a body of saltwater evaporates what two minerals are left behind?
After water evaporation sodium chloride (NaCl) remain as a solid residue.
What is left behind when a solution is heated?
A solid insoluble residue remain after the evaporation of water.
Why do salts leave behind during an evaporation?
Only the water molecules are evaporated. Any solids are left behind.
What is the evaporation of water from leaves to plant?
evaporation helps by taking left over water evaporation helps by taking left over water
How is crystallization technique better than simple evaporation technique to get a pure solid?
Crystallisation is the most common method to purify soluble solids. It is preferred over evaporation to dryness as many substances decompose upon strong heating. Also, when all the water is removed during evaporation, any soluble impurities will be left on the crystals (eg. sugar decomposes to become carbon when it is heated strongly). The shape and size of crystals can be controlled by controlling variables such as cooling rate and evaporation rate.In crystallisation, water is removed by heating the solution. Heating stops when a hot saturated* solution is formed. The resulting solution is left to cool and the dissolved solid will then be formed as pure crystals. This is because the solubility of the solute decreases as the temperature drops. At a lower temperature, less solute can be dissolved in the solution.
