What is the formula for the ionic compound formed from the lead (ii) ion and the chloride ion?

PbCrO₄

Explanation:

Ionic compound:

It is the compound which is formed by the transfer of electron from one atom to the atom of another element.

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

Chemical equation:

Pb²⁺ + CrO₄²⁻ → PbCrO₄

Lead cation react with chromate anion and form ionic compound lead chromate.

The lead cation has + 2 charge while chromate has - 2 charge thus both are equal and cancel each other. The over all compound will be neutral.
