Question

Determine which of the following substances dissolve in water by filling out the table

below.

Substance Nature of

substance

Soluble/Insoluble

Miscible/Immiscible

Explanation for

answer

Acetone (CH 3 COCH 3 )

Silver nitrate (AgNO 3 )

Sulfuric acid (H 2 SO 4 )

Methylamine (CH 3 NH 2 )

n-pentane C 3 H 12

CH 3 CH 2 COOH

Answer 1

All substances dissolve in water, besides n-pentane C 3 H 12. Acetone (CH 3 COCH 3 ) and CH 3 CH 2 COOH dissolve in water, because carboxyl-groupes form hydrogen-bonds with a moleculas of water. Silver nitrate (AgNO 3 ) and Sulfuric acid (H 2 SO 4 ) are ionic compounds. Methylamine (CH 3 NH 2 ) forms the donor-acceptor bonds with hydrogen of water molecula. And n-pentane C 3 H 12 can't form any bonds with water moleculas.
