What substances give a positive tollens test?
When adding the aldehyde or ketone to Tollens' reagent, the test tube is put in a warm water bath. If the reactant under test is an aldehyde, Tollens' test results in a silver mirror. If the reactant is a ketone, it will not react because a ketone cannot be oxidized easily. A ketone has no available hydrogen atom on the carbonyl carbon that can be oxidized - unlike an aldehyde, which has this hydrogen atom.
How do you distinguish between acetic acid and formic acid?
Formic acid gives positive result in both tollen's test and fehlings test. but acetic acid doesnot.
What is the colour of formic acid?
Chemical formula for formic acid is HCOOH. It is an organic acid compound. Formic acid is colorless.
Is an ant sting acidic or alkaline?
An ants sting is Formic Acid
Is HCHO a formic acid?
No, CH2O is formaldehyde and is not formic acid. HCOOH is formic acid. The key to the answer is that formaldehyde has only one oxygen but formic acid has two in its carboxylate group.
