- SCIENTIFIC INQUIRY • INTERPRET THE DATA A Minnesotagardener notes that the plants immediately bordering a walkwayare stunted compared with those farther away. Suspectingthat the soil near the walkway may be contaminated from saltadded to the walkway in winter, the gardener tests the soil. Thecomposition of the soil near the walkway is identical to thatfarther away except that it contains an additional 50 mM NaCl.Assuming that the NaCl is completely ionized, calculate howmuch it will lower the solute potential of the soil at 20°C usingthe solute potential equation:ΨS = -iCRTwhere i is the ionization constant (2 for NaCl), C is themolar concentration (in mol/L), R is the pressure constant[R = 0.00831 (L · MPa)/(mol · K)], and T is the temperature inKelvin (273 + °C).How would this change in the solute potential of the soilaffect the water potential of the soil?
