Expert Answer
We need to find the oxidation number of phosphorus in so let us first break the compound into ions so the ions would be as follows and now taking only ion let us assign the oxidation number of phosphorus as x and oxygen have the oxidation number -2 and overall charge on the ion is -3 so now just arrange the values as so phosphorus has the oxidation number = +3 2.) We need to find the ion concentration The ion product of water, Kw, is the product of the concentrations of H+ and OH- ions in water at a given temperature. At 25°C, Kw is equal to we are given So now
