road salt has been dropped on grass. keep osmosis in mind, what would happen?

answer:
since the road salt is hypertonic solution and therefore the water in the grass would diffuse into the road salt thus causing the grass to die.

Is this right? What should I add?

Your understanding is mostly correct, but let me further explain the process using the concept of osmosis.

When road salt is dropped on grass, it creates a hypertonic solution. Hypertonic means that there is a higher concentration of solute (in this case, salt) outside the grass cells compared to the inside of the cells. Osmosis is the movement of water molecules from an area of low solute concentration to an area of high solute concentration through a semi-permeable membrane.

In this scenario, the road salt acts as the solute, and the water inside the grass cells acts as the solvent. Since the concentration of salt is higher outside the grass cells, water molecules will tend to move out of the cells through osmosis.

As water leaves the grass cells, it disrupts the balance of water and nutrients necessary for the proper functioning of the cells. This loss of water can lead to dehydration and shrinkage of the cells, causing the grass to wilt and eventually die.

Therefore, it is important to note that the hypertonic solution created by road salt leads to water loss from the grass cells via osmosis, ultimately causing harm to the grass.
