Why is mercuric acetate employed in non aqueous titrations and by what mechanism does it work?
Mercuric acetate is used in non-aqueous titrations because it is soluble in organic solvents. It functions as an oxidizing agent, converting the species being titrated into a form that can be easily detected by a color change or other indicator. This mechanism involves the transfer of electrons between the analyte and mercuric acetate, resulting in the formation of a colored complex that signals the end point of the titration.

Why is acetic acid used in the synthesis of phenylmercuric acetate by combining mercuric acetate with benzene?
Acetic acid is used in the synthesis of phenyl mercuric acetate by combining mercuric acetate with benzene to create an antifungal used in agriculture. It is both flammable and extremely explosive.
Why mercuric acetate is used in non aqueous titration?
During non-aqueous titration of amine salts, the halide ions, namely: chloride, bromide and iodide are very weakly basic in character so much so that they cannot react quantitatively with acetous perchloric acid. In order to overcome this problem, mercuric acetate is usually added (it remains undissociated in acetic acid solution) to a halide salt thereby causing the replacement of halide ion by an equivalent amount of acetate ion, which serves as a strong base in acetic acid as shown below: 2R.NH2.HCl ↔ 2RNH3 + + 2Cl - (CH3COO) 2 Hg + 2Cl- → HgCl2 + 2CH3COO- undissociated 2CH3COOH2+ + 2CH3COO- ↔ 4 CH3 COOH
What is the mechanism for the conversion of camphene to isobornyl acetate?
The conversion of camphene to isobornyl acetate involves a process called acetylation. In this process, camphene reacts with acetic acid in the presence of a catalyst, typically sulfuric acid, to form isobornyl acetate. This reaction involves the addition of an acetyl group (CH3CO) to the camphene molecule, resulting in the formation of isobornyl acetate.
What are the elements in acetate?
The elements in acetate are carbon, hydrogen, oxygen, and sodium in the case of sodium acetate(CH3COONa) *** Acetate: C2H3O2^-1
What role does the acetate leaving group play in the mechanism of nucleophilic acyl substitution reactions?
The acetate leaving group in nucleophilic acyl substitution reactions acts as a good leaving group, facilitating the departure of the acyl group and allowing the nucleophile to attack the carbonyl carbon, leading to the formation of a new acyl compound.

What is the formula for strontiym acetate?
Hence its acetate formula should be similar to calcium acetate [CH3COO]2 Ca strontium acetate is [CH3COO]2Sr.
Is acetate a salt?
Acetate is not a salt; it is the conjugate base of acetic acid. It is commonly used in the form of sodium acetate or calcium acetate, which are salts.
What are the buffers used in complexometric titration?
Buffers commonly used in complexometric titrations include ammonium acetate-acetic acid, ammonia-ammonium chloride, and potassium hydrogen phthalate. These buffers help maintain a relatively constant pH during the titration process, ensuring accurate and precise results.
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)
