Even after being stirred a solution has solute crystals at the bottom. if the temperature remains constant what happens when more solute is added to the solution

It becomes a supersaturated solution

Explanation:

Due to the fact that the crystals can no longer dissolve and adding more solute to the same temperature will continue not to dissolve the crystals making it more and more saturated leading to supersaturated solution

b) mutualism

hope this : )

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
