Unlike donated blood, these “blood substitutes” do not require refrigeration and have a long shelf life. The effect of temperature depends strongly on the properties of the particular system and also on the temperature. The solubility of most solid or liquid solutes increases with increasing temperature. If the diver ascends too quickly, the rapid pressure change causes small bubbles of N2 to form throughout the body, a condition known as “the bends.” These bubbles can block the flow of blood through the small blood vessels, causing great pain and even proving fatal in some cases. The use of first-aid instant cold packs is an application of this solubility principle. decreased in the CMC with increasing the number of oxyethylene group(4, 20). The understand that the solubility of a solid may increase or decrease with increasing temperature. A According to Dalton’s law, the partial pressure of \(O_2\) is proportional to the mole fraction of \(O_2\): \[P_A = X_A P_t = (0.21)(1.00\; atm) = 0.21\; atm \nonumber\], B From Henry’s law, the concentration of dissolved oxygen under these conditions is, \[CO_2=kP_{O_2}=(1.27 \times 10^{-3}\; M/\cancel{atm}) (0.21\; \cancel{atm}) =2.7 \times 10^{-4}\; M \nonumber\]. g water) 10.0 10.0 10.0 82.0 11.301 29.50 4.0 14.0 … Effect of Temperature on the Solubility of Gases. As the temperature increases, the solubility of most of the gases decreases owing to the greater tendency of the gas to expand in comparison to the solvent. In exothermic reactions, increasing the temperature decreases the solubility of the solute. 11-14 years ; 14-16 years; Use. Charles Ophardt (Professor Emeritus, Elmhurst College); Virtual Chembook. In this lab, students will collectively create a solubility curve for KCl in water. Investigation: The effect of temperature on solubility.
