Question

xCl2 (g) + yKI (aq)= zKCl (aq) + I2 (s). What are the values of x, y and z?

Answer 1

Answer:

x=1, y=2, z=2

Explanation:

The equation shows the oxidation of KI to KCl to liberate chlorine and is used in the identification because in a starch iodide paper(KI+starch) chlorine displaces iodine in KI to liberate I2 and hence turns the paper blue black. This is because as soon as iodine comes in contact with starch solution, the paper turns blue black.

Equation:- Cl2 + 2KI ---------> 2KCl + I2

Answer 2

Answer:

The balanced reaction is as follows:

The balanced reaction is as follows:3Cl2+6OH−→ClO3−+5Cl−+3H2O

The balanced reaction is as follows:3Cl2+6OH−→ClO3−+5Cl−+3H2OHence, X=3, Y=5.
