Examples are soluble salts as: sodium chloride and other chlorides, nitrates, sulfates, phosphates etc.
Rivers dissolve salt from the Earth rocks and transport this salt to seas and oceans.
It is not recommended to dissolve these salts; they are elements for the clinical analysis.
when salts dissolve in water they undergo dissociation into corresponding ions.
Many salts are soluble in water.
Water dissolve many ionic salts because water has a polar molecule.
Soluble salts are dissociated in water.
Mostly carbonates and bicarbonates while seawater is dominated by sodium and chlorine.
Yes they do
Polar salts are easily dissolved in water.
This is not mandatory: some salts are very soluble, some salts are very insoluble.
No, it is not possible.
Dissolved salts are transported by the rivers.
