why we don't heat the evaporating dish directly over a Bunsen flame if we heat the salt solution for salt?

Question

a beaker of water is heated. The water from the salt solution evaporates and changes from a liquid to a gas. when all water evaporated, solid salt remains in the evaporating dish?

Answer 1

The heat of a Bunsen flame would be too strong. You would get boiling, spattering, and loss of salt from the evaporating dish. There isalso an outside chance you could crack the dish.

Answer 2

no in fact this is one thank you to purify water and get the impurities (like salt) out and create stable eating water. it incredibly is termed "distilling" in case you seize the steam coming off the heated water and funky it and catch the drops of water in yet another bottle. The salt and different stuff keeps to be interior the unique field and the forged water strikes from steam back into water interior the recent field. on the different hand, in case you enable each and all the water evaporate off you would be left with the salt - this is how salt is "synthetic" - nevertheless is in some countries. cities called "Salinas" are often places the place the evaporation occurred in super shallow swimming pools close to the sea. Ocean water replaced into became in to salt for nutrition guidance and cooking. so a procedures as distilling is in touch it incredibly is a low tech yet costly way of purifying water. opposite osmosis is the extra suitable way now a days. - besides the reality that neither thank you to purify water makes stable water to drink as a slow weight loss application- any stable stuff is likewise bumped off like stable minerals. gudluk
