Question

Phyaical characteristic of salt is anion or cation

Answer 1

: we can identify the cation and anion in a given salt by using physical characteristics like color, taste, odor, melting point, solubility product etc..

from colors we observed : potassium dichromate, K2Cr2O7 ( orange) , potassium permanganate,KMnO4(violet), Ferric oxide, Fe3O4 (black), Ferrous sulphate , FeSO4.7H2O(green) etc.. here you can see same cation for different anions having different colours.

Answer 2

Salts are compounds that contain both cation and anion i.e H+ and OH- ions.
