When formic acid is treated with potassium hydroxide (KOH), an acid-base reaction occurs, forming a carboxylate ion. For the mechanism, draw the curved arrows as needed. Include lone pairs and charges in your answer. Do not draw out any hydrogen explicitly in your products.

See explanation

Explanation:

The reaction between formic acid and potassium hydroxide is an acid base reaction.

Remember that an acid base reaction yields salt and water only.

If you look at the curved arrow mechanism shown, you will discover that the hydroxide ion from KOH abstracts a proton from the acid to yield potassium formate and water

pure substance: iron,copper

impure substance: water,charcoal

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
