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 does the rate of evaporation of an aqueous solution decrease with the 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.
Do bases tend to decrease the pH of a solution?
No, the bases increase the pH of an aqueous solution.
Can the concentration of a substance change if it is an aqueous solution?
Yes. An aqueous solution means that at least one solute is dissolved in water. You can increase the concentration by adding more solute, or you can decrease the concentration by adding more water.
What evaporates water from an aqueous solution containing a precipitiate?
Heating contribute to the water evaporation.

What statement about Arrhenius acids is FALSETheir aqueous solutions are electrolytesTheir water solutions are called aqueous acids They increase the concentration of hydroxide ions in aqueous solutionThey are molecular compounds with hydrogen ions?
The answer is: They increase the concentration of hydroxide ions in aqueous solution.
As the temperature of an aqueous solution increases what does the concentration of gas dissolved in the solution do?
An aqueous solution has 0.0070 gram of oxygen dissolved in 1000. grams of water. calculate the dissolved oxygen concentration of this solution in parts per million?A. 17ppm B. 27ppm C. 7ppm D. 7ppm
What happens to OH in an aqueous solution when H3O increases?
As the concentration of H₃O⁺ increases in an aqueous solution, the pH decreases, shifting the equilibrium of the autoionization of water to the left. This results in a decrease in the concentration of hydroxide ions (OH⁻) in the solution.
Water is a solvent in a(n) what solution?
'An Aqueous' solution. NB The word 'aqueous' comes from Latin ; 'aqua' meaning 'water'.
What is the term for a solution made in water?
The term for a solution made in water is an aqueous solution.
How do you separate hydrated CuSO4 from its aqueous solution?
One common method to separate hydrated CuSO4 from its aqueous solution is through the process of evaporation. By heating the solution, water evaporates leaving behind solid CuSO4. The solid can then be filtered to separate it from the remaining liquid.
