A water-testing device has two reservoirs separated by a partially permeable membrane. Reservoir P contains 2 g of salt per 100 cm³ of solution. Reservoir Q contains 8 g of salt per 100 cm³ of solution.
Which observation will result from osmosis?
The amount of salt in reservoir P will increase as salt crosses the membrane.
The liquid level in reservoir Q will rise as water crosses the membrane.
The liquid level in reservoir P will rise as water crosses the membrane.
The liquid levels will stay the same as equal amounts of water cross each way.
