Above a salt content of 24.7 g/kg, as temperature decreases

Question

Quizplus · Accepted Answer

Water density typically increases as it cools, up to the point of freezing. However, the presence of salt affects both the density and the freezing point of water. As the salt content increases, the freezing point of water decreases. This is because the dissolved ions interfere with the formation of ice crystals, a phenomenon known as freezing point depression. Therefore, both statements in option D are correct: water density increases as temperature decreases up to the freezing point, and the freezing temperature decreases as salt content increases.
