Vedclass · Answer

(B) The water potential $(\psi_w)$ of pure water is defined as zero. When solutes are added to pure water,they bind to water molecules,reducing the free energy of the water and thus lowering the water potential. This is known as the solute potential $(\psi_s)$,which is always negative. Similarly,insoluble colloids (like proteins or starch) also bind water molecules through adsorption,which reduces the number of free water molecules available to move,thereby decreasing the overall water potential. Therefore,the presence of both solutes and insoluble colloids leads to a decrease in water potential.

How is water potential $\psi$ affected by the presence of solutes and insoluble colloids?
