From lead acetate the acetate anion is a weak base that will react with stronger acids than acetic acid is ( pKa < 4.77) to form is conjugated acid.
The Pb2+ ion may react with the acid's anion if a precipitate can be formed (e.g. PbSO4, PbCl2, Pb3(PO4)2 and many others are insoluble)
What else can I help you with?
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.
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.
Is phenyl acetate or butyric acid more polar?
Phenyl acetate is less polar than butyric acid. This is because butyric acid has more polar functional groups present (carboxylic acid) compared to phenyl acetate (ester).
What is the name of LiC2H3O2?
lead acetate
Lead acetate chemical formula?
Lead acetate's chemical formula is Pb(CH3COO)2
What is the molar mass of : (a) lead acetate, Pb(CH3 COO)2?
also known as lead acetate, lead diacetate, plumbous acetate, sugar of lead, lead sugar, salt of Saturn, or Goulard's powder, is a white crystalline chemical compound with a sweet taste. It is made by treating lead(II) oxide with acetic acid.
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 happens when lead acetate is added to concentrated sulfuric acid?
Pb2+ --> PbSO4(s)Concentrated sulfuric acid will 'burn' or 'carbon'ise acetate (CH3COO-) to Carbon black, CO2(g) and H2O(l) and some other intermediate products.Be very carefull! Very exothermic!You should never work with concentrated acids un-gided and unprotected!.
Is calcium acetate an acid or a base?
Ca-acetate is a weak base, conjugated with a weak acid: H-acetate (i.e. acetic acid)
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.
Is acetate the same to acetic acid?
No. Acetate is the anion (negative ion) derived from acetic acid. Acetic acid is CH3COOH. Acetate is CH3COO-. Acetate ions exist in minute concentrations in a solution of acetic acid and can also be produce by neutralizing acetic acid with a base.
What does strong acid plus metal acetate give?
When a strong acid reacts with a metal acetate, it typically forms the corresponding metal salt and acetic acid. For example, if hydrochloric acid reacts with sodium acetate, it would produce sodium chloride and acetic acid. This reaction involves the displacement of the anion of the acid by the acetate anion.
What is Acetate in vinegar?
acetic acid or hydrogen acetate.
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.
Is potassium acetate a weak acid?
No, potassium acetate is a salt formed by the reaction of a strong base (potassium hydroxide) with a weak acid (acetic acid). Potassium acetate is neutral and does not act as an acid in aqueous solutions.
Solubility Vinyl acetate in acid acetate?
Vinyl acetate is slightly soluble in acetic acid due to the formation of hydrogen bonds between the acetate groups. However, it may not be highly soluble in acetic acid compared to other solvents.
Is magnesium acetate is a base?
Magnesium acetate in its aqueous state is neutral or slightly acid.
