What element in the amino acid is detected to be present in the lead acetate test?
The element that is detected in the lead acetate test for amino acids is sulfur. This test is used to identify the presence of sulfhydryl (thiol) groups in amino acids, which react with lead acetate to form a precipitate.
What compounds are responsible for the result of lead acetate test?
The lead acetate test is used to detect the presence of sulfides in a sample. This test results in the formation of a black precipitate of lead sulfide (PbS) when lead acetate is added to a solution containing sulfide ions. Lead sulfide is insoluble and appears as a dark-colored solid.
What is the Formula of the colored precipitate obtained in the sulfur test or lead acetate test?
The colored precipitate obtained in the sulfur or lead acetate test is lead sulfide, and its chemical formula is PbS. This reaction is commonly used to confirm the presence of hydrogen sulfide gas or sulfide ions in a solution.
What is the colored precipitate obtained in the sulfur test or lead acetate test?
The colored precipitate obtained in the sulfur test or lead acetate test is lead sulfide (PbS). Lead sulfide is a black precipitate that forms when hydrogen sulfide gas reacts with lead ions in a solution, indicating the presence of sulfide ions in the original sample.
Which makes the lead acetate paper black?
Lead acetate paper turns black in the presence of hydrogen sulfide gas. Hydrogen sulfide reacts with lead acetate to form lead sulfide, which is black in color. This reaction is commonly used as a test for the presence of hydrogen sulfide gas.
What compound is responsible for the results in the lead acetate test?
Hydrogen sulfide is tested with lead acetate.
Methionine give a positive sulfur test?
yes

The element that is detected in the lead acetate test for amino acids is sulfur. This test is used to identify the presence of sulfhydryl (thiol) groups in amino acids, which react with lead acetate to form a precipitate.
In lead acetate test what element in the amino acid is detected to be present in this test?
The lead acetate test is used to detect the presence of the sulfhydryl (thiol) group in amino acids, particularly cysteine. When lead acetate solution is added to a sample containing a sulfhydryl group, a black precipitate of lead sulfide forms, indicating a positive test for the presence of sulfhydryl groups.
What amino acid will yield a positive result with lead acetate test?
Cysteine will yield a positive result with the lead acetate test due to the formation of lead sulfide. Lead sulfide appears as a black precipitate when cysteine is present in the solution.
What is the Formula of the colored precipitate obtained in the sulfur test or lead acetate test?
The colored precipitate obtained in the sulfur or lead acetate test is lead sulfide, and its chemical formula is PbS. This reaction is commonly used to confirm the presence of hydrogen sulfide gas or sulfide ions in a solution.

Which makes the lead acetate paper black?
Lead acetate paper turns black in the presence of hydrogen sulfide gas. Hydrogen sulfide reacts with lead acetate to form lead sulfide, which is black in color. This reaction is commonly used as a test for the presence of hydrogen sulfide gas.
Why cotton wool is dip in the lead acetate solution which is use in the limit test for arsenic?
Cotton wool is dipped in lead acetate solution in the limit test for arsenic because lead acetate forms a yellow precipitate with arsenic, making it easier to detect the presence of arsenic in the sample being tested. The cotton wool helps to trap any arsenic present by absorbing the lead acetate solution along with the formed precipitate.
What are the chracteristics of lead sulfide?
Lead sulfide is a black solution. It is insoluble in water and is a precipitate. The principle of the lead acetate test is the formation of lead sulfide.
Which turns lead acetate paper black?
Hydrogen sulfide (H2S) turns lead acetate paper black. Lead acetate paper is used as a test for the presence of hydrogen sulfide gas. If the paper turns black upon exposure to a gas, it indicates the presence of hydrogen sulfide.
