Rock salt lowers the freezing point of water, causing the ice to melt. This melting process requires energy, which is absorbed from the surroundings, resulting in a cooling effect.

Why do we get pure salt from rock salt?

Pure salt is obtained from rock salt through a process called evaporation. Rock salt contains impurities and other minerals that are removed when the salt is dissolved in water and then evaporated, leaving behind pure salt crystals. This process helps to separate the salt from any impurities present in the rock salt.


Is rock salt soluble?

Ofcourse,rock salt is soluble in water as it is the salt obtained from pieces of rock made by salt.only the impurities in the rock salt will not dissolve impurities may be dirt,dust or salt.There may be some other soluble material also in the rock salt.


Is rock salt flammable?

No, rock salt is not flammable. It is a non-combustible material that is used primarily for culinary purposes and as a de-icer on roads.


How would rock salt form from a solution?

Rock salt forms when a solution containing dissolved salt is allowed to evaporate, leaving behind the solid salt crystals. The process of evaporation causes the water to leave the solution, resulting in the precipitation of salt crystals. These crystals can then accumulate and form deposits of rock salt over time.


How a rock can form by evaporation?

A rock cannot form solely through the process of evaporation. Rocks are typically formed through processes such as cooling and solidification of magma/lava, sedimentation and compaction of sediment particles, or metamorphism (changes in existing rocks due to heat and pressure). Evaporation primarily concentrates dissolved minerals in water bodies, leading to the formation of minerals like salt or gypsum, but not rocks.
