Why does table salt dissolve rapidly in water?

Answer 1

Because the crystals of the table salt are smaller and the speed of solving depend on the surface area of the material (smaller crystals mean a greatest surface area); dissolution takes place at the surface of the solid.

Answer 2

Table salt is made up of smaller clumps of particles than rock salt. To dissolve, particles of the salt must come in contact with the solvent particles than rock salt, resulting in faster dissolving. (Copied from the Pure Substance & Mixtures Section of some Nelson Literacy Science Text Book)

Answer 3

Maybe because the particle size is bigger than regular salt.

Assuming that by "salt" you mean table salt, then salt would dissolve faster in water when compared to rock salt because table salt, which is granulated, has much more surface area exposed. Since the water can only dissolve the salt that is on the surface (it can't reach into the middle of a large chunk of salt) the increased surface area results in the salt dissolving faster.

Answer 4

It is because crushed salt is smaller than rock salt and it can be easily dissolve in the water..

Answer 5

Yes, sea salt dissolves faster. Im not sure why but me and another kid from school decided to test this theory for a science project.

Answer 6

Because powder salt has a larger surface area than rock salt.

Answer 7

Because the crushed salt is already crushed and it became small,while the uncrushed salt is so big,so it takes a long time to be dissolve on the water

Answer 8

Both are polar compounds.

Answer 9

no, people

Answer 10

uncrushed salt
