Question
true or false
6. Solubility of gases in water generally decreases at lower temperature. Answl 7. Solubility of gases in water generally decreases at lower partial pressure. Answer: 8. Solubility of solids in water generally increases at lower temperature. Answer: 9. Addition of a nonvolatile solute to a solvent raises the vapor pressure and reduces the boiling point of the solution. Answer: 10. The semipermeable cell membrane in red blood cells permits water and small molecules such as salts to pass through. Answer:Explanation / Answer
Ans 6 : false
Gases are more soluble at lower temperatures than the higher.
Ans 7 : True
The more the partial pressure of gas above the water surface , the more the gas is soluble in it.
Ans 8 : False
Solids are soluble at higher temperatures , as the heat provides energy for the hydration of ions .
Ans 9 : False
Addition of solute decreases the vapour pressure and increases the boiling point.
