Correct Answer: Sodium chloride
Solution : The correct answer is Sodium chloride.
Sodium chloride, known as table salt, is the mineral salt that dissolves the most in ocean water. The salty taste of the ocean is caused by sodium chloride, which makes up the majority of the dissolved salts in seawater. In addition to sodium chloride, ocean water contains various other dissolved salts, including magnesium chloride, calcium sulfate, and potassium sulfate. These combined salts contribute to the salinity of seawater, which typically averages around 3.5% by weight.
