What are the precautions for conical flask?
Usually they are handled by gripping the neck of the flask from the side. Get in the habit of never allowing you hand to be over the opening in the neck. Sometimes the fumes coming out through the throat of the flask can be hot or corrosive and burn you.
Round flask with long neck?
You could be referring to a florence flask or a volumetric flask.See the Related Questions links to the left for more information.
Why does the egg go in to the flask when heated?
When an egg is heated, the protein present within it(the egg white), called albumin gets denatured. This is because protein structures break at high temperatures. As a result, the liquid albumin forms a thick white mass.
What is the history of the erlenmeyer flask?
The Erlenmeyer flask is named after the German chemist, Emil Erlenmeyer, who developed the instrument in 1861.
What are the safety precaution when using erlenmeyer flask?
When handling an Erlenmeyer flask you should always keep it away from your face and body, and make sure you donâ??t break it. You should also be careful not to spill the material inside of the flask.
A flask is weighed and has a mass of 50.0 grams Then 2.0 grams of sodium metal is added to the flask Chlorine gas is pumped into the flask This allows the sodium metal to react completely with c?
The sodium metal will react with chlorine gas to form sodium chloride. The reaction involves a single displacement reaction where sodium replaces chlorine in its diatomic form to form NaCl. The final mass of the flask will increase by 2.0 grams due to the formation of sodium chloride.
Why is sodium hydroxide added into the conical flask containing a analgesic or aspirin?
to decrease ph
To combine equal numbers of sodium and chloride atoms in a flask how much Chloride would you have to add if you added 23 Grams of sodium?
23 grams of Na is close enough to 1 mole not to matter, so add 35.45 grams of Chloride ion to the flask.
Why is it that the compound of hydrogen and chlorine not a mixture?
The properties of hydrogen chloride differ markedly from both hydrogen and chlorine, and you cannot see either of the original elements in the hydrogen chloride liquid. In contrast, if you simply mix hydrogen and chlorine in a flask you will still have a gas which is coloured yellowish by the chlorine.
Can sodium hydroxide be stored in a Erlenmeyer flask?
It is not recommended to store sodium hydroxide in an Erlenmeyer flask because the strong base can react with the glass, causing potential damage or breakage of the flask. It is better to store sodium hydroxide in a container made of a material that is compatible with strong bases, such as high-density polyethylene or glass specifically designed for chemical storage.
What is in chlorine?
Chlorine= Cl2 idk exactly what that formula means but thts the chemical make-up for it. it has the atomic number 17 and is in halogen group on the periodic table if that helps any. hope i helped y'all at least a little<3333
How did Edouard Benedictus made plexiglass?
He was working in his lab when he dropped a flask his assistent had not cleaned. he dropped it from about 20 feet up so he was expecting it to be shattered, instead it was broken but still clung together.
What reacts readily with acids such as hydrochloric?
Small amounts of chlorine gas can be made in the laboratory by putting concentrated hydrochloric acid in a flask with a side arm and rubber tubing attached. Manganese dioxide is then added and the flask stoppered. The reaction is not greatly exothermic. As chlorine is denser than air, it can be collected by placing the tube inside a flask where it will displace the air. Once full, the collecting flask can be stoppered.
When do you add sodium hydroxide into the conical flask containing the analgesic?
Sodium hydroxide is typically added slowly to the conical flask containing the analgesic after the analgesic has been dissolved in a solvent like ethanol. The sodium hydroxide solution is added drop by drop while stirring to form a clear solution, indicating the completion of the reaction.
Process to make homemade table salt?
1-Take some sodium, some chlorine gas, and some sand. (The amount of the salt you'll get will be as same as the sodium you used) 2-Put the sand and the chlorine in a lab glass. (Preferably Florence of Erlenmeyer type) 3-Cut a piece of sodium and put it in. (Not a huge piece, it's gonna make an exothermic reaction, that means it's gonna BURN!) 4-Drop some drops of water on the sodium, cover the flask and back up. (FAST!) 5-Wait for the reaction to happen. It's gonna burn for a little while. 6-You have your salt. 2Na(s)+Cl2(g)=2NaCl(s)
What happens when a thermo flask contains some ice cubes?
The ice cubes will help to keep the contents of the thermos flask colder for a longer period of time. The thermos flask's insulation will prevent heat transfer from the surroundings, helping to maintain the temperature of the ice cubes and the contents of the flask. Over time, the ice cubes will melt and help to cool the contents of the flask.
Why do you add sodium hydroxide into the conical flask containing the analgesic tablet?
Sodium hydroxide is added to the conical flask to create a basic environment, which helps to break down the tablet and facilitate the reaction necessary for the analysis of the active ingredient. This reaction is important for quantifying the amount of the active ingredient present in the tablet.
