Why diffusion is slowest in solid and fastest in gas?
Diffusion takes place with slowest rate in the case of solids. The rate of diffusion is almost negligible in solids. Since the particles of solid have lowest kinetic energy so they do not move. Hence, diffusion takes a long time in the case of solid.
Does diffusion occur in solid?
For diffusion to work, the particles must be able to move around. This means that diffusion does not happen in solids – the particles in a solid can only vibrate and cannot move from place to place.
Which substance diffuses the fastest?
At any given temperature, small, light molecules (such as H2, hydrogen gas) diffuse faster than larger, more massive molecules (such as N2, nitrogen gas) because they are traveling faster, on the average (see heat; kinetic-molecular theory of gases).
Why is carbon dioxide more soluble in blood than oxygen?
Carbon dioxide is more soluble in blood than is oxygen; about 5 to 7 percent of all carbon dioxide is dissolved in the plasma. Carbon dioxide has the ability to attach to hemoglobin molecules; it will be removed from the body once they become dissociated from one another.
Why is CO2 less soluble in warm water?
The bond between carbon and oxygen is not as polar as the bond between hydrogen and oxygen, but it is polar enough that carbon dioxide can dissolve in water.
Are CO2 and so2 soluble in each other?
The results show that the total solubility of SO2 + CO2 in water varies exponentially with respect to SO2 concentrations, i.e., at low concentrations of SO2, total changes in solubility of the CO2 in water is negligible.
What happens to pH When CO2 is dissolved in water?
Aqueous carbon dioxide, CO2 (aq), reacts with water forming carbonic acid, H2CO3 (aq). Carbonic acid may loose protons to form bicarbonate, HCO3- , and carbonate, CO32-. In this case the proton is liberated to the water, decreasing pH. The complex chemical equilibria are described using two acid equilibrium equations.
Can water absorb CO2?
Ocean plants take in the carbon dioxide and give off oxygen, just like land plants. The ocean is great at sucking up CO2 from the air. The ocean absorbs carbon dioxide from the atmosphere wherever air meets water. Wind causes waves and turbulence, giving more opportunity for the water to absorb the carbon dioxide.
Does pH affect solubility of CO2?
The maximum total amount of CO2 that may dissolve in water is a function of pH. This is because as pH changes, the fraction of the total dissolved CO2 as CO2 (aq) also changes.
What forms when carbon dioxide dissolves in water?
Carbon dioxide dissolves in water and slowly reacts with water to produce carbonic acid.
