Synthesis of zinc iodide
How well do your results agree with the law of conservation ofMass ( use percent difference to compare)
% composition of Zn and I:
Convert mass Zn to moles
Convert mass I2 reacted to moles
Using the molar ratios determine the emperical formula for zinciodide
Given:
Mass of empty test tube#1: 22.28g
Mass of test tube #2 + boiling stones: 23.10g
Zn reactant:
Mass of tube #1 + Zn + Iz: 26.33g
Mass of I2: 2.06
Zn
Mass of test tube#1 + remaining Zn: 23.78g
Mass of Zn consumed in the reaction 0.49g
Zinc iodide
Mass of test tube#2+ zinc iodide: 25.64
Mass of Zinc iodide:0.69
