Why does the rate of evaporation of an aqueous solution decreases with increase in humidity?
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.
Why dissolving Ammonium nitrate(NH4NO3) in water is an endothermic although the temperature of the solution decreases?
The energy needed to support the endothermic reaction is supplied by the solution; thus the solution temperaturedecreases.If the reaction were exothermic, the solution temperature would increase.
Why is a solution heated during evaporation in the laboratory?
Because evaporation is accelerated after increasing of the temperature.
What happens to concentration of the hydronium ions as the pH decreases?
The concentration of hydronium ions (H3O+) increases as the pH decreases. This is because pH is a measure of the concentration of hydronium ions in a solution. As the pH decreases, the solution becomes more acidic, leading to an increase in hydronium ion concentration.
Does the density of a solution increase or decrease on evaporation?
The density of a solution typically increases on evaporation because as the solvent evaporates, the remaining solute becomes more concentrated in the solution, leading to a higher density.

How does an increase in temperature affect the ability of a gas to go into solution?
it decreases solubility.... by damion /\
Does cold ringer's solution increase or decrease heart rate?
In decreases the heart rate.
To increase the concentration of a solution?
You can increase the concentration of a solution by adding more solute (solid, liquid, or gas) to the solvent or by removing some of the solvent by evaporation. Stirring or heating the solution can also help dissolve more solute and increase the concentration.
How is concentration of hydronium ions affected when a solution of acid is diluted in water?
When a solution of acid is diluted in water, the concentration of hydronium ions decreases. This is because the dilution increases the volume of the solution, causing the same amount of acid to be spread out over a larger volume. As a result, the concentration of hydronium ions in the solution decreases.
What happens to the pH when carbon dioxide levels increase?
When carbon dioxide levels increase, the pH of a solution decreases. This is because carbon dioxide reacts with water to form carbonic acid, which lowers the pH of the solution.
Can evaporation make a saturated solution unsaturated?
No, evaporation will most likely make the solution supersaturated
If a hot concentrated solution is cooled some of the solute comes out of the solution what is this process called?
This process is called precipitation. It occurs when the solubility of the solute decreases as the solution cools, causing the excess solute to come out of the solution in the form of solid particles.

How do you separate a solution?
Two ways are evaporation and distillation.
