HOW TO USE THE EVAPORATING DISH?

Do have to use activated charcoal to kill mold smell?
No. Generally smells are caused by wet substances evaporating. Activated charcoal will absorb the moisture and reduce and eliminate the smell. Baking powder, baking soda, salt, and other substances that readily absorb moisture will accomplish the same.
Can you use Shoe string to make a salt crystal?
No, you pretty much have to use salt.
When do you use salt water?
we use salt water while one gets dehaidretion
How do you get the salt out of salt water?
Boil the water and collect the steam - that water will be salt free. Boil the water in a partial vacuum and this will be more efficient since this lowers the boiling point. Reverse Osmosis is another way by getting the salt water to leave the salt molecules on the other side of the membrane. It works like the human gut. The third way is to use the Sun to heat a pan of salt water with a conical tent of clear polythene above the pan. Pure water condenses on the polythene and runs down to an annular dish surrounding the salt pan.
Why do you use an evaporating basin to get salt from seawater instead of a beaker?
to increase the surface area of evaporation
Which of these could you use to separate a mixture of sand and salt?
Salt is soluble in water where as sand is not. Using a fine paper filter in a funnel the salt can be removed from the sand by rinsing the mixture with water and then the salt can be retreived by evaporating the water. Hope I'm not doing your homework for you

What is distillation and where is it used?
Distillation is evaporating a liquid and collecting the condensed form. It is used to purify water and make liquids pure and to also separate a mixture, for example, get salt from salt water and have then in separate containers. People in wineries use it to make alcohol stronger.
Why use an evaporating dish instead of a beaker for sublimation?
Evaporating dishes are used to boil solutions. Crucibles are used to heat solids very strongly.
What do you use when you want to separate salt from water without the water evaporating?
Ocean survival kits once used a chemical that would bind to the salt and sink to the bottom of a container. The less-salty water at the top of the container would be drinkable. Life rafts today may carry "reverse osmosis pumps" that force seawater through a permeable membrane to separate out the salt.
How can you separate the calcium chloride from the water?
Use a zink sulphate test
Is iodized salt the worse salt to use?
Iodized salt is the best to use !
How can you physically separate a mixture of iron fillings table salt and white sand?
by putting all of the substances on a sheet or plate and then using a magnet underneath to pull the iron fillings away. then for your table salt and white sand you just use small mesh and voila! all wrong ... 1st, use magnet to separate the iron filling from the mixture of sand with table salt 2nd add water to dissolve the salt from the mixture with the sand and filtrate the liquid sand has separated from mixture of salt 3rd place the the filtrate liquid to a burner with a evaporating dish, the water will be evaporate and the remaining residue would be the small crystal particles which is the salt.
How do you use evaporating-dish?
The name is clear: it is used to evaporate a liquid to obtain the solid residue.
Is direct heating advisable when evaporating NaCl solution?
no, it is more safe to use water bath :)
