Which of the following is an application of the principle of constant proportions? a) Siliceous ooze accumulates on the ocean floor as it is being dissolved because it accumulates siliceous tests faster than seawater can dissolve them. b) Calcium carbonate dissolves at an increasing rate with increasing depth until the calcite compensation depth is reached. c) The concentration of a single major constituent can be measured to determine the total salinity of a water sample. d) Increasing pressure increases the number of water molecules in a given volume and inhibits the number of ice crystals.

Answer: c) The concentration of a single major constituent can be measured to determine the total salinity of a water sample.

Explanation: The law of constant proportions is also known as Proust's law or as the law of definite proportions. It states that chemical compounds are consists of elements that are present in a fixed ratio by mass.

No matter how much the salinity increases or decreases in the ocean, the number of ions proportional to each other remains constant.
