Question

Is the upper layer of solution the yellow color layer is more salinity or less salinity, explain?

Answer 1

The yellow color layer in a solution generally indicates a higher salinity level. This is because yellow coloration in a solution usually comes from the presence of dissolved organic compounds or impurities, which are more concentrated in high salinity solutions. So, the upper layer of solution being yellow in color likely has a higher salinity level compared to the lower layers or other solutions with different color layers.
