What is the valency of sodium phosphate?
The valency of sodium phosphate is determined by the charges of the individual ions in the compound. Sodium (Na) is a group 1 element with a valency of +1, while phosphate (PO4) has a charge of -3. To balance the charges in the compound, three sodium ions (each with a valency of +1) are needed for every one phosphate ion (with a valency of -3). Therefore, the valency of sodium phosphate is +1 for sodium and -3 for phosphate.
