A Science 30 student is provided with three unknown substances. He is told that the identities of them are methanol(CH3OH)

methanoic acid(CHOOH)

and methyl methanoate,(CHOO-CH3)

To identify what each of the unknown substances is, he performs a conductivity, litmus,
and odour test on each of the substances.

Conductivity Test
1 - Positive
2- Negative

Litmus Test

1- no change
2- red turns blue
3 - blue turns red

Match the descriptions below to the correct results from the tests above:

42. Conductivity of methanol

43. Litmus test of Methyl methanoate

44. Conductivity rest of Methanoic acid

45. Litmus test of Methanoic acid
