Explanation:
1) Salt is a white cubic crystal . The color of salt depends upon the purity of salt.
2)It is odourless but has a strong salty taste.
3) Solubility in water is different at different temperatures.
4) It is hygroscopic.
5) Melting point of salt is 800.8 degree Celcius.
6) Boiling point of salt is 1465 degree Celcius.
7) The refractive index of salt is about 1.542
8) The specific gravity or relative density of salt is 2.165
9) The critical humidity of salt at 20 degree Celcius is 75.3%
10) The size of crystal of salt varies.
11) The chemical molecular formula salt is NaCl.
12) Chemically the composition of sodium and chlorine in salt is 1:1
13) Sodium is a metal and chlorine is a non-metal
that's why ionic bond is formed.
14) Highly soluble in water due to contain less energy than hydration energy.
15) pH is 7 because formed by both strong acid and strOng base.
16) No change in litmus paper.
17) Electrically neutral due to both atoms contains onepaired electron i.e valency.
18) Non-combustible i.e. low toxicity.
19) Hardness is 2.5 on MOH scale of hardness.
20) Efflorescence is property salt.
