WebDec 10, 2011 · Solvent is a substance with dissolving capability, thus can dissolve another substance. Solvents can be in a liquid, gaseous or solid state. Solute is a substance that is soluble in a solvent in order to form a solution. Solutes can be in liquid, gaseous or solid phase. So, solubility is the ability of a solute to dissolve in a solvent. WebThe difference ∆ of 1.0 %w/w corresponds to a density change of 0.0071 g/cm³, thus the accuracy of the NaCl solution is: (1.0 x 0.000005)/0.00710 = 0.007 %w/w. This is the average accuracy for the overall range as defined above, and only true assuming the relation of density to concentration is linear.
