What is Lassaigne's extract?
Lassaigne test is a method in qualitative analytical chemistry used to detect halogens, sulfur or nitrogen in organic compounds.
Is acetaminophen will give positive result to Lassaigne's test and ferrox paper test?
yes
What weight is dangerous?
the weight which you can't handle is dangerous
Why would it be dangerous to handle even small amount of radium?
Radium is strongly radioactive and emit alpha, beta and gamma radiations. These radiations are very dangerous for all the beings.
Why don't you heat a test tube continuously?
To avoid dangerous tension in the glass.
Mechanism of lassaigne's test?
Name alternative method for lassaigne's test
What is Lassaigne's extract?

Why is ferric ferrocyanide prussian blue in lassaignes test?
Prussian test is a part of lassaigne test, since prussain test used for nitrogen detection while lassaigne used for detection of halogens sulphur and nitrogen in organic compounds
Is acetaminophen will give positive result to Lassaigne's test and ferrox paper test?
yes
Why is lassaigne's test dangerous?
Lassaigne's test involves the use of concentrated sulfuric acid and heating, which can lead to potential chemical hazards such as acid burns, release of toxic gases, and potential fire hazards. Incorrect handling or insufficient precautions during the test can lead to serious accidents and injuries. It is important to conduct this test in a well-ventilated laboratory and to wear appropriate personal protective equipment.
Does hydrazine answer the test for nitrogen in Lassaignes test?
lassaigne's test is not given by hydrazine as it cannot produce NaCN
When was Jean Louis Lassaigne born?
Jean Louis Lassaigne was born on 1800-09-22.
Why only sodium is used in Lassaigne's test?
because of its electropositive nature. it is cheap also. although potassium can be used but it is costly... and lithium is less electropositive... Lassaigne's test is a test for the detection of halogens, nitrogen and sulphur in an organic compound. These elements are covalently bonded to the organic compounds. In order to detect them, these have to be converted into their ionic forms. This is done by fusing the organic compound with sodium metal. The ionic compounds formed during the fusion are extracted in aqueous solution and can be detected by simple chemical tests. The extract is called sodium fusion extract or Lassaigne's extract.
Why lassaigne's test failure in diaso compound?
Nitrogen is a good leaving group. therefore,the gas is expelled when the compound is heated. no formation of sodium cyanide.
What has the author J Lassaigne written?
J. Lassaigne has written: 'Spanish painting from Velazquez to Picasso' 'Spanish painting from the Catalan frescos to El Greco'
What weight is dangerous?
the weight which you can't handle is dangerous
