Illustrate the law of reciprocal proportions from the following data: KCl contains 52.0% potassium, KI contains 23.6% potassium and Icl contains 78.2% iodine. |

Answer» Solution :In KCL: Potassium 52.0% Chlorine (100-52)=48% In KI: Potassium 23.6%. IODINE (100-23.6)=76.4% 23.6 parts of potassium combine with 76.4 parts of iodine 52.0 parts of potassium will combine with (76.4/23.6)`xx52.0=168.3` parts of iodine. The RATIO of masses of chlorine and iodine which combines with same mass of potassium =48:168.3 or 1:3.5 In ICI: Iodine =78.2% and chlorine `=(100-78.2)=21.8%` The ratio of chlorine and iodine in ICI=21.8:78.2=1:3.5. Hence, the DATA ILLUSTRATE the law of reciprocal proportions. |
