Question

potassium chloride criss cross method

Answer 1

Potassium Chloride by Criss cross method

Answer 2

The formula of Potassium Chloride by the criss-cross method is KCl.

• The valency of potassium K is +1 and that of Chlorine Cl is -1.
• The charge on K is +1 and on Cl is -1.
• The formula of potassium chloride can be obtained by the criss-cross method:

                      K     Cl

    Valency    +1      -1

                 By cross-multiplying, we get

                        KCl

• So, the formula of the compound Potassium Chloride is KCl.
• KCl is an ionic compound.

Hence, the formula of Potassium Chloride by the criss-cross method is KCl.
