Answer:
Explanation:
1. what is rock salt?
It is knwon as saindha namak
This is the common name for the mineral "halite". Its chemical formula is NaCl. You might know this substance as table salt. and... Actually, rock salt is not K2SO4; it is NaCl. It can have impurities of gypsum (CaSO4) and sylvite (KCl) but it is very rare to find potassium sulfate as a mineral, although occasionally polyhalite (K2Ca2Mg(SO4)4.2H2O) is found associated with rock salt deposits.
2. how is it formed?
It is typically formed by the evaporation of salty water (such as sea water) which contains dissolved Na+ and Cl- ions.
Hi friend.......
Halite more commonly known as Rock salt is a mineral formed from sodium chloride. It's chemical formula is NaCl and this also includes other variations of salt such as common salt and table salt. Rock salt tends to be the industrial name used for halite it.forms as isometric crystals and is typically colourless or white, but may also be other colours depending on the amount and type of impurities contained within it. The salt occurs in beds of sedimentary evaporite minerals. This is caused by large lakes and seas drying up. These salt beds can be hundreds of metres deep. Halite crystals form very quickly in some rapidly evaporating lakes. England was covered by inland seas over 200 million years ago which helped create the layers of salt that are mined today. When very hot temperatures in the area evaporated the waters very slowly, they left large salt deposits under the earth. In the UK as the water evaporated and the salt crystals started to form they got their brownish colour from sand blown in from eastern deserts. However other geological influences mean the rock salt's colour can sometimes go from clear, to pink, to dark brown.
Hope helps....
