The valency of potassium dichromate is +6. This is because potassium has a valency of +1, and each chromium atom in the dichromate ion has a valency of +6.
The commercial name of K2Cr2O7 is potassium dichromate.
The valency of potassium permanganate is +7.
Valency of k=1+ valency so4=2- after crisscrossing the valencies, we get- chemical formula- k2so4
The valency of potassium ion (K+) is +1, zinc ion (Zn2+) is +2, and chloride ion (Cl-) is -1. Valency represents the combining power of an element in a compound, based on its ability to gain, lose, or share electrons.
The formula for sodium dicromate is Na2Cr2O7
