Question

One of the following combinations which illustrates the law of reciprocal proportions is: (A) N 2 O 3, N 2 O 4, N 2 O 5 (B) NaCl, NaBr, NaI (C) CS 2, CO 2, SO 2 (D) PH 3, P 2 O 3, P 2 O 5

Tardigrade Admin · Accepted Answer

In CO 2, 12 parts by mass of C combine with 32 parts by mass of oxygen while in SO 2, 32 parts by mass of S combine with 32 parts by mass of oxygen. The ratio of masses of carbon and sulphur which combine with a fixed mass of oxygen is 12: 32 or 3: 8 . In CS 2, 12 parts of carbon combines with 64 parts by mass of sulphur therefore 12: 64, i.e., 3: 16 ∴ The ratios are (3/8): (3/16) or 2: 1
