Solute concentration of potatoes
WebThe weight decreases when the sucrose concentration increases because of the hypertonic solution absorbs the water out of the potatoes. Calculations: Ψ ( solute potential) = – iCRT. Ψ. = -1 (0.27) (.0831) (273+20) Ψ. = -6.57. The ionization (i) is for the sucrose, which stays at 1 because it does not ionize in water. WebMar 26, 2024 · Molecules become constantly in motion as a result for an cell's stored kinesthetic force, which causes them to bump to respectively other and move inbound irregular new directions. Diffusion is the movement by molecules from on area of wherever there represent multiple (high concentration) to an area where on am fewer (low concen
