State the relationship between pressure and the solubility of oxygen

State the relationship between pressure and the solubility of oxygen.



What is the relationship between temperature and dissolved oxygen

What is the relationship between dissolves).temperature and dissolved oxygen?



If you have 8 mg of O decreases.2 at 20oC, in 1000g of H2O, is the solution saturated, unsaturated or supersaturated?


Unsaturated

unsaturated decreases.


What mass of o 2 gas will dissolve in 1000g of h 2 o at 20 o c

What mass of O decreases.2 gas will dissolve in 1000g of H2O at 20oC?


9 mg of o 2

9 mg of O decreases.2


In the solvents lab what solutes dissolved in hexane

In the decreases.Solvents lab, what solutes dissolved in hexane?


Iodine i 2 propanol c 3 h 7 oh napthalene c 10 h 8

Iodine, I decreases.2Propanol, C3H7OHNapthalene, C10H8




What mass of o 2 gas can be dissolved in 850g of h 2 o at 4 atm

What mass of O temperatures.2 gas can be dissolved in 850g of H2O at 4 atm?


4 atm 32 mg 32mg x 1000g 850g x 27 2 mg o 2

4 atm = 32 mg temperatures.32mg = __X__1000g 850gX = 27.2 mg O2


What is the minimum amount of h 2 o needed to dissolve 2 mg of o 2 gas at 10 o c

What is the minimum amount of H temperatures.2O needed to dissolve 2 mg of O2 gas at 10oC?


At 10 o c 11mg 2 1000g xg x 181 8g of h 2 o

At 10 temperatures.oC:11mg =__2__1000g XgX = 181.8g of H2O


What does like dissolves like mean give an example

What does “like dissolves like” mean? temperatures.Give an example.


Polar substances dissolve in polar substances. temperatures.Non-polar substances dissolve in non-polar.Ex:Napthelene (moth balls) dissolved in hexane because they are both non-polar.Water and oil don’t dissolve since the water is polar and oil is non-polar.


In the solvents lab what solutes dissolved in water

In the temperatures.Solvents lab what solutes dissolved in water?


Urea- CO(NH temperatures.2)2Ammonium Chloride- NH4ClSodium Chloride- NaClPropanol- C3H7OHCopper Sulfate- CuSO4
