Reaction of aniline with glacial acetic acid?
Aniline reacts with glacial acetic acid to form N-acetylaniline as the primary product. This reaction involves the acetylation of the amino group of aniline by the acetic acid to form the acetylated product. The reaction is usually carried out in the presence of a catalyst like sulfuric acid to facilitate the acetylation process.
Why is concentrated ethanoic acid or acetic acid called 'glacial'?
"Glacial" in the context of acetic acid refers to its high freezing point of 16.7°C, which is relatively close to room temperature. This characteristic gives it a crystalline appearance resembling ice, hence the term "glacial" to describe its concentrated form.
What does the presence of the peat and soil layer in the glacial till tell you?
The presence of peat and soil layer in glacial till suggests that there was a period of time after the glacier retreated when vegetation was able to grow, indicating a warmer climate. This layer can provide information about the environment and climate conditions during that post-glacial period.

What does the presence of peat in glacial till tell us?
The presence of peat in glacial till suggests that the area was once covered by wetlands or marshes where peat formed. This can give clues about the past environmental conditions and the type of vegetation that was present in that area.
Are there any other names for acetic acid other than vinegar?
Yes, they are:* Ethanoic acid (its systematic name)* E 260 (its E number for food preservative)* Glacial acetic acid (its concentrated form)* AcOH (its abbreviation)
What is the pH of glacial water melt?
The pH of glacial water melt is typically around 6.8 to 7.4, which is slightly acidic to neutral. The pH can vary depending on factors such as the surrounding geology and presence of minerals.
What evidence would prove that an area was eroded by a glacier?
Evidence of glacial erosion includes U-shaped valleys, striations or grooves on rocks caused by the movement of the glacier, glacial polish on rocks, and moraines (deposits of glacial till). These features indicate the past presence and movement of a glacier in the area.
Where can ethanoic acid found?
Ethanoic acid is CH3CO2H, also known as Acetic acid and is a weak organic acid. The structure of ethanoic acid is CH3COOH. It is found in vinegar ("vinegar" is Old French for "sour wine"). Vinegar is used as a food flavoring and preservative. Ethanoic acid is used to make a polymer called acetate rayon. Acetate rayon fibres can be woven to make clothing and fabrics. A reaction that produces ethanoic acid: ethanol + oxygen -> ethanoic acid + water. C2H5OH(aq)+ O2(g) ->CH3CO2H(aq) + H2O(l)
Why does the presence of the peat and the soil layer in the glacial till tell you you?
The presence of peat and soil layers in glacial till suggests that the area has undergone historical periods of vegetation growth and soil formation, indicating a climate that was conducive to supporting plant life. This information can be used to infer past environmental conditions and changes in the landscape over time.
3-methyl-1-butanol plus glacial acetic acid?
The reaction between 3-methyl-1-butanol and glacial acetic acid is an esterification reaction, producing the ester 3-methylbutyl acetate. This reaction is typically catalyzed by an acid, such as sulfuric acid. Water is produced as a byproduct during this reaction.
Can you see the formation of glacial trough?
Yes, glacial troughs are U-shaped valleys that form through the erosion of moving glaciers. They have steep, straight sides and a flat bottom that was carved out by the glacier over time. The presence of a glacial trough indicates past glaciation in an area.
