Challenging Plants: Soil Science - Practicals

Description

The nature of soil particles (inorganic and organic) and of soil water affects plant growth and, in particular, the availability of nutrients essential for the growth of quality crops in high yield. An understanding of the media in which plants grow helps scientists to exploit their potential.

Practical investigation of how the distribution of zinc ions between soil and an aqueous solution depends on temperature. It uses the analytical method Zinc by zincon assay. Using lnKd = -ΔHo/(RT) + ΔSo/R ( the Van’t Hoff equation) and ΔGo = ΔHo - TΔSo, values for ΔHo, ΔSo and ΔGo may be estimated. Student version.
