Why does common salt become sticky during rainy season?

Question

Does it have something to do with humidity?

Answer 1

impure common salt has affinity to H2O just like sugar or CuSO4

....and this is called water of crytallisation

.....eg CuSO4.XH2O....

so that's why in high humidity u feel salt or sugar rather sticky...for copper sulphate at times it can change to liquid totally,,,coz it has a high affinity for H2O...

Answer 2

yes it has to do with the humidity,,, I always put a egg noodle in my shaker and it helps a lot

Answer 3

put a few grains of rice in the salt shaker.it will help.

Answer 4

yes the humidity in the air causes the salt to become moist and sticky... the moisture makes the salt sticky because of the salt being wet lol....
