Evaporated water can be made pure under controlled conditions, but in nature it is frequently impure. When water evaporates, it does leave behind any solid contaminants such as metals and salts, so it gets purified to that extent. But evaporated water can contain some liquid and gaseous contaminants that make it impure. Perhaps you have heard of "acid rain", which is evaporated water contaminated with carbon dioxide, sulfur oxides, nitrogen oxides, and hydrogen chloride gases. Evaporated water can also be contaminated with some volatile water-soluble organic compounds.

A chemist dissolves an ionic compound in water. the vapor pressure of the solution is?
When an ionic compound dissolves in water, it dissociates into its constituent ions, increasing the number of solute particles in the solution. This phenomenon leads to a decrease in the vapor pressure of the solution compared to that of pure water, as described by Raoult's Law. The extent of the vapor pressure reduction is proportional to the concentration of the dissolved ions. Therefore, the vapor pressure of the solution is lower than that of the pure solvent.
Which water evaporate fast salt water or pure water?
pure waterDiscussionDissolving something in water which does not evaporate easily will make the mixed solution less likely to evaporate than pure water. The more stuff you add to it, the less likely it will evaporate.Adding salt to water makes ions in solution and these ions reduce the vapor pressure of the solution compared to pure water. The lower the vapor pressure of a liquid or solution, the slower it will evaporate. This effect is also related to boiling point elevation and freezing point depression.
What is water saturation temp?
Water saturation temperature is the maximum temperature at which water can exist in a stable liquid state at a given pressure. It is the temperature at which water vapor in equilibrium with liquid water exerts a partial pressure equal to the vapor pressure of pure water at that temperature.
What has the highest boiling point pure water or salty water?
Salty water (saltwater) has a higher boiling point than pure water, as the presence of salt in the water raises its boiling point. This is because the salt interferes with the ability of the water molecules to escape as vapor, requiring higher temperatures for boiling to occur compared to pure water.
What form of water is the most abundant at any time in the water cycle?
water vapor
Is water vapor pure substance or mixture?
Water vapor is a pure substance.
Is water vapor a mixture or pure substance?
Water vapor is considered a pure substance because it is composed of molecules of only one type of substance, which is water.
A pure solvent has a vapor pressure the vapor pressure of a solution A.EQUALTO B.LOWER THAN C.higher than?
A solution has a higher vapor pressure than a pure solvent. This is why salt water boils faster than pure water.
What is vapor pressure of water?
The vapor pressure of pure water at 25 degrees Celsius is 23.8 torr.
How much water will a car that burns hydrogen exhaust?
if it runs on pure hydrogen then the only exhaust will be pure water vapor.
How will the vapor pressure of pure water compare to an aqueous solution of sodium chloride?
The vapor pressure of pure water will be higher than that of an aqueous solution of sodium chloride at the same temperature because the presence of sodium chloride reduces the number of water molecules available to evaporate, lowering the vapor pressure of the solution. In other words, the solute particles in the solution interfere with the evaporation of water molecules, resulting in a lower vapor pressure compared to pure water.
Is water vapour a mixture element or a compound?
Pure water vapor is a compound, just as liquid water is.
Is rainwater is pure form of water or distillted water?
It is based as salt water but then turned into pure water. 1. The ocean water evaporates into water vapor leaving all the salt and other chemicals behind 2.The water vapor turns into clouds 3.The clouds build up in water so much they rain. So yes rain water is pure
How do you turn salt water to pure water?
Distillation is the easiest way. Heat the water until it evaporates, leaving the salt behind. Catch and condense the water vapor into pure water.
The presence of water vapor in pure air?
Water vapor in pure air is typically present in small amounts and can vary depending on factors such as temperature and humidity. It plays a crucial role in the Earth's water cycle and helps regulate the atmosphere's temperature through the greenhouse effect. Too much water vapor can lead to cloud formation and precipitation.
What happens to Vapor pressure of water when mixed with sodium chloride?
The vapor pressure of water decreases when mixed with sodium chloride. This is because the presence of sodium chloride particles in the water lowers the vapor pressure of the solution compared to pure water at the same temperature.
How could a sample of pure water be obtained from the drink?
You could distill the water from the lemon drink and condense the water vapor and collect the water in a container.
