Why does the rate of evaporation of an aqueous solution decrease with the increase in humidity?
Wiki User
∙ 7y ago
As the humidity increases, the partial pressure of water vapor in the atmosphere (above the solution being evaporated) also increases. This results in more energy being necessary for the liquid water to evaporate, thus the higher the humidity, the longer it will take for evaporation of an aqueous solution to take place. This is essentially based on Dalton's Law of Partial Pressures.

Will the rate of evaporation of an aqueous solution decrease with increase in humidty?
Humidity is basically the amount of water vapour in the air. And evaporation is the vaporization of water into water vapour. So when the humidity is high there are already plenty of water molecules in the air so the water which gets vapourized into water vapour takes time to fill the gaps in the atmosphere and thus rate of evaporation is slow.

If a solution is diluted will the absorbance decrease or increase?
decrease
How can you change concentration?
To increase the concentration of a solution, you can decrease the amount of solvent by boiling off, or by evaporation, or you can simply add more solute. Conversely, to decrease the concentration, you can add more solvent.
Will the normality of an h2c2o4 solution increase or decrease of the solution is stored in a clear bottle in a lighted room?
Oxalic acid is a stable compound.
Why the rate of evaporation of an aqueous solution decrease with increase in humidty?
At limes of low humidity fluids evaporate more quickly because they can be easily taken up by the surrounding environment, at 100% humidity evaporation stops, evaporated water can be measured as relative humidity

Will the normality of an NaOH solution increase or decrease if the solution is exposed to air for prolonged periods?
If the solution volume remains unchanged, the normality will decrease as the NaOH will react with CO2 present in the air. Of course, if the solution volume is not held constant and if the evaporation rate is sufficient to concentrate the solution - it could also increase (effectively raising the normality of the remaining solution).
If a solution is diluted will the absorbance decrease or increase?
decrease
What happens to copper sulphate solution after 2 days at 21c?
It would begin crystalising and would decrease
Does a base increase or decrease the pH of a solution?
A base will increase the pH of a solution as it will lower the available H+ ions.
Do bases tend to decrease the pH of a solution?
No, the bases increase the pH of an aqueous solution.

In a pressure chamber filled with gas above a liquid solution a decrease in volume causes?
AN increase n pressure, an increase in gas concentration in the solution
If an acid is added to a solution does the H plus concentration increase or decrease?
It increases.
What would you do to increase or decrease the concentration of the nutrient solution?
The amount of water you add.
