. The sum of all the oxidation states of all the atoms in H3PO4 is ____________.

Interpretation Introduction

Interpretation:

Complete the sentence with appropriate term.

The sum of all the oxidation states of all the atoms in H3PO4 is _______

Concept Introduction:

Oxidation state is also known as oxidation number. It is defined as the numbers which are assign to the elements in a chemical combination and number represents the electrons which an atom can share, lose or gain to form chemical bonding with an atom of another element.

Therefore, transfer of electrons refers to the oxidation state.

Explanation

The given molecule is H3PO4 ,

According to the rules of oxidation number, the oxidation state of oxygen and hydrogen is -2 and + 1 respectively. Thus, the oxidation state of phosphorus should be determined. For neutral atom, the overall charge on molecule is equal to zero.

Let x be the oxidation state of phosphorus.

3+x+4(-2)=0

x=+5

By adding, all the oxidation states of all
