What else can I help you with?
When would you prefer to use an air cooled condenser with no water running through it during organic chemistry distillation?
Air condenser can be used when the boiling point of the solvent is very high, as the air temperature will to sufficient to condense the solvent vapour. Water condenser is generally used when the solvent boiling temperature is less e.g., water, ethanol etc.
Is the process of removing salt from water?
Salt is prepared by evaporation of water.
What is the problem with using a simple distillation apparatus a glass tube?
The problem with distillation is how to turn all of the hot vapour back into liquid. A simple distillation experiment using just a glass tube as a condenser, rather than a Liebig one, loses most of the steam.
What is it called when water vapour becomes liquid?
Water vapour changes back into its liquid form during the process known asCondensation.
To condense is a physical or chemical change?
Condensation can be a physical process whereby a vapour becomes a liquid e.g. the 'steam' (water vapour) from your shower condenses on the bathroom window and runs down as water to form a puddle on the windowsill. Warm air can hold more water than cold air - the warm, vapour-laden air is cooled as it comes in contact with the colder glass and can hold less vapour so the surplus appears as water on the glass. In chemistry there are 'condensation reactions'
What is the process that happens when a vapour is cooled?
It's called condensation when vapour cools and turns into liquid.
How do you clean seawater?
One method is distillation. Sea water is allowed to eveporate and the vapour is then cooled so that it condenses into distilled water.
What processes take place in distillation?
In distillation water is boiled to make steam (or heated to near boiling point to be precice) & the resulting vapour is cooled to provide a pure product, be that water or spirit.
What is the name of the process that separates crude oil into more useful substances?
Crude oil is separated by fractional distillation. The components of crude oil are separated by a process which is known as fractional distillation. Crude oil is made of different components whose sizes, weights and boiling temperatures are different from each other. When the crude oil is heated with high pressure steam at a high temperature, it boils and forms vapour. The vapour enters a fractional distillation column and settled in the trays of the column. The trays have holes in them which raise the contact time among the vapour and liquids. The vapour rises in the column and cools, the hotter substances settle at the bottom of the column and the cooler substances rise to the top of the column. The substances in the vapour condense and the fractions of liquid collect in the tray and pass to condensers and storage tanks.
Would distillation or filtration produce the purest water from river waterGive a reason?
Because distillation produces vapour and impuritites can not leave with the vapour
What state is water in during the process of evaporation?
water vapour
What is an enriching section in a distillation column?
It is the top section of the distillation column. The section where the vapour leaves the column to the condenser.
Can water vapour be turned back into liquid water?
Yes water vapour or steam can be reverted back to water through the process known as condensing. If the steam is collected and cooled it will turn to water droplets that can be collected as water.
What happens with water vapor when its cooled?
when water vapour is cooled it condenses and falls as rain
What is the purple substance of the iodine after heating?
It is vapour formed during the process of sublimation.
What must the components of a solution have different in order for distillation to work?
Volatility, vapour pressure
When does sublimation happen?
When unsaturated vapour is cooled down under freezing point
