WebbOsmotic pressure is the lowest pressure that inhibits the inward flow of a pure solvent into a solution that is separated from it by a semipermeable membrane. The quantity of solute particles affects osmotic pressure. It varies in proportion to the solution's molarity. So, this is the correct option. π π π = iMRT.

WebbA solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Weak acid/base. Weak acids/bases only partially dissociate in water. Finding the pH of a weak acid is a bit more complicated.
