I have a box of salt that hardened from humidity or something.?

Question

Is there anyway to make it so its not all stuck together in a block, and I can pour it again?

Answer 1

The salt is hygroscopic that is why it absorbs water from the atmosphere and gets soft, which turns hard on keeping for long period. It can be turned back by :
- use of mechanical force to loosen it and then put in the sun to get dried;
- use of temperature of the order of 40-45 deg C for getting the water evaporated;
- Use of protective material so that it does not come in contact with water and get hardened;
- Use of in-active material like rice to avoid hardening.

Answer 2

Salt is hygroscopic meaning that it readily absorbs H2O from the atmosphere. Many chemicals are like this and what chemists do is store them in dessicators. When they are clumped like your salt the only thing that could be done is to heat it in an oven at at least 120C. This is probably not the smartest thing to do unless you have a lab oven so it would be much wiser to just buy another container of salt. In restaurants you quite often see rice in salt shakers. I think this helps keep the salt from absorbing H2O.

Answer 3

Put rice in salt box to protect them. Grind the solid salt and dry in sun else buy new salt.

Answer 4

i heared if u put some rice (uncooked) inside the box it helps!

Answer 5

just use the hammer
