Name polyatomic ions for the following ? ?
po4 -3
c2h3o2 -1
no2 -1

what state would water be when formed on the product side of a reaction, solution, liquid, aqueous? ?
any would be appreciated

PO₄³⁻ is phosphate, C₂H₃O₂⁻ is acetate and NO₂⁻ is nitrite.

When water is formed as a product of a reaction, of the temperature of the reaction is high, then water vapour evolves, and if the temperature is less than boiling point of water, then the water forms an aqueous solution.

Polyatomic ions are the ions or radicals that take part in a reaction as a whole and possesses a charge of its own.

The PO₄³⁻ is phosphate ion which is formed by deprotonation of phosphoric acid, where the charge on phosphate atom is 5+.

The   is the acetate ion which is formed by deprotonation of acetic acid.

The NO₂⁻  is nitrite ion which is formed by deprotonation of nitrous acid. The charge on nitrogen atom is +1.

Water is often the by product of a reaction. Now if the reaction occurs above the boiling point of water then the water evaporates off the solution as vapour. If the reaction occurs below the boiling point of water and the components are miscible in water, then it forms a solution with the components.
