Explanation:
Detailed explanation-1: -Following is the descending order of salinity found in seawater: Calcium carbonate > sodium chloride > magnesium chloride.
Detailed explanation-2: -In fact, as table 1 shows, 86% of the dissolved material in sea water is sodium chloride, followed in decreasing order of concentration by magnesium, sulphate, calcium and potassium.
Detailed explanation-3: -The average content of salts in seawater is 26 g per litre. The maximum concentration of dissolved salts in seawater can go up to 35 g per litre, after that the concentration does not increase.
