Silver Dichromate Charge

Silver dichromate is a chemical compound with the molecular formula Ag2Cr2O7. It contains two silver ions (Ag+) and two dichromate ions (Cr2O7 2-), each of which has a charge of -2.

The total charge of the compound can be calculated by adding up the charges of its component ions. Since there are two silver ions, each with a charge of +1, the total positive charge from the silver ions is +2. Likewise, since there are two dichromate ions, each with a charge of -2, the total negative charge from the dichromate ions is -4.

Therefore, the overall charge of silver dichromate is the sum of these charges:

+2 (from the silver ions) + (-4) (from the dichromate ions) = -2

This means that silver dichromate has a net negative charge of -2, making it an anionic compound.
