How do you get clean water from muddy water through evaporation?
The condensed water is cleaner because impurities are not evaporated.
Is salt water ok to drink after evaporation?
Vapors must be condensed to obtaindrinking water. Salt water is not good to drink.
Why is the conical flask only rinsed with distilled water in the titration procedure?
Yes. By adding water to rinse, you will be changing the concentration of the thing you are titrating, and so your calculation will be off. If you have material on the walls of the flask, just gently stir the flask and let the solution in the flask wash anything off the walls. I do not believe this is true. Once you add an amount of reactant into your flask adding more water will not change the number of moles of reactant that are present in the flask. The titrant will react in the mole ratio for that particular reaction so water doesn't play a role. You can rinse the flask and even use water to get part of a drop into your flask for a more accurate titration.
Use of erlenmeyer flask?
Physical DescriptionAn Erlenmyer Flask (named after Emil Erlennmeyer) is a common piece of laboratory glassware since 1861. It is also known as as a conical flask or E-flask. It has a conical body, flat base and a narrow cylindrical neck. The flask is usually marked to indicate the approximate volume of their contents.The flask is chosen to replace a beaker if there is a need to stopper the contents. The narrow neck is sized to accept standard rubber stoppers or corks.The conical shape and narrow neck facilitates stirring by swirling.The small neck reduces evaporates losses. The neck may be fitted with side tubes to allow the extraction of produced gasesThe flat bottom improves stability on lab benches. A Florence flask has a similar overall use but is more unstable because the body is round and the base is smaller.UsesErlenmeyer flasks are used for:pH tit rationsthe preparation of mixtures which must be mixed without Starr
How much water do Petunia plants need?
The soil in which the plant is placed must be kept 'towel-wet'. This is a certain dampness which is cold to the touch but does not drip when the pot is lifted. A test for the moisture of your plant would be how easy it is to lift. If it is too light it may need water. Another sign is the color of the soil. This should be kept at a dark brown/black color rather than the light brown of dry soil.
Why must not the condensed water drip into the flask?

Must a flask be a good conductor of heat?
so as to keep the flask hot hereby keeping the hot water inside the flask hot.
How can you get fresh water if it evaporates?
After evaporation vapors must be condensed.
Is salt water ok to drink after evaporation?
Vapors must be condensed to obtaindrinking water. Salt water is not good to drink.
A 0.200M solution of sodium carbonate Na2CO3 is made by dissolving 5.30g of the solid in water and making up the mark in a standard flask What volume must the flask be?
Flask is something that holds the sweeet nectar of alcohol
What are condensed domains?
It actually means compressed or concentrated. Example: the power must not be condensed.
What must be present so that clouds could form?
Water vapor and heat must be present for clouds to form. The water is evaporated from the ground and collected into a cloud.

When boiling water will it remove all the contaminants?
To ensure all contaminates are removed, the water must be distilled by boiling, the water vapour led off, and then condensed back into water into a clean vessel.
To distil sea-water you must first.?
collect sea water in distilling flask. boil water. steam escapes, salt remains behind. use physical means to separate physical mixtures.
Kind of water must be used in medical preparations?
The water used in medical preparations differs from the water that a human normally consumes. Water used in medical preparations is distilled and sterilized.
