What did emil erlenmeyer discover?
In 1880, German chemist Emil Erlenmeyer, formulated what is known as the Erlenmeyer Rule, which states that "All alcohols in which the hydroxyl group is attached directly to a double-bonded carbon atom become aldehydes or ketones".
When can an Erlenmeyer flask be used instead of a beaker?
I my experience the Erlenmeyer flask is better for certain things than others.... what I mean is that is has labeled measurements on the side and the increments are based on the size of the flask but the volumetric flask is better is you want to dilute a solution at a certain volume to find....molarity they both have good qualities it just depends on what you want to use it for.
What is a flask used for?
AnswerA flask is a container for storing or carrying liquid.It also keeps the liquid at the same temparature over a number of hours. A flask is nominally used for carrying liquids in it and usually of the alcoholic nature, and is usually referred to as a hip flask as it is carried in a pocket either the front or back.
What is a conical flask used for?
An Erlenmeyer flask, commonly known as a conical flask or E-flask, is a widely used type oflaboratory flask which features a conical base and a cylindrical neck. They are usually marked on the side (graduated) to indicate the approximate volume of their contents. It is named after the German chemist Emil Erlenmeyer, who created it in 1861.
What are erlenmeyer flasks and florence flasks used for?
See the two Related Questions to the left for a description of each one. They are different in both shape and function.Florence flasks have round bottoms and no gradations indicating volume. Erlenmeyer flasks are conical in shape and have gradations depicting volume on the side.
What is a Erlenmeyer filter?
This is a conical flask from glass or plastic, frequently used in all chemical laboratories; the Erlenmeyer flask may contain reagents, collect filtrates, labware for a chemical reaction, it is used for titration, etc. It is not a filter.

Can a titration be performed starting with the base in the Erlenmeyer flask Explain why or why not?
Yes. I dont usually use the first person in an answer but I do this all the time at work. Adding base or a very alkaline brine layer to an Erlenmeyer flask, weighing it, and then titrating with standard acid is a standard procedure.

What is the volume capacity of a flask?
The answer depends on the flask: they are not all the same size.

This is a conical flask from glass or plastic, frequently used in all chemical laboratories; the Erlenmeyer flask may contain reagents, collect filtrates, labware for a chemical reaction, it is used for titration, etc. It is not a cylinder.
What is an Erlenmeyer flask used for in chemistry?
Physical DescriptionAn Erlenmeyer 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 evaporative 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 titrationsthe preparation of mixtures which must be mixed without stirringDisadvantages:The Erlenmeyer is often stirred with a glass rod even though swirling is more often suggested. Inexperience students often do this while holding the flask at near eye level. A tap with the rod will knock the bottom off dumping the (usually nasty poisonous, hot and corrosive) contents all over the students legs.Erlenmeyer flasks are used to measure, mix, and store liquids.

What is the use of the conical flask?
it is used during titration for carrying or taking the reactants e.g. acids,base etc.
Why is a round bottomed flask used in fractional distillation rather than a flat bottomed flask?
A round bottomed flask is used in fractional distillation because it allows for better distribution of heat, resulting in more uniform heating and better separation of components in the mixture. The round shape also promotes smoother boiling and condensation processes within the flask.
