Topic 3.4

Temperature and Water Potential

Values of RT at various temperatures and the Ψs values of solutions of different solute concentrations are presented below in Web Table 3.4.A. For ionic solutes that dissociate into two or more particles, cs must be multiplied by the number of dissociated particles to account for the increased number of dissolved particles. This does not apply to H+ or OH ions released by dissociation of an acid or base, because these ions contribute to the solvent rather than diluting it.
