3Zn(OH)₂ + 2H₃PO₄ → Zn₃(PO₄)₂ + 6H₂O
Explanation:
To balance this equation, we must understand that in every chemical reaction, the number of atoms is usually conserved.
The total number of atoms on the reactant and product sides must be equal and the same.
Zn(OH)₂ + H₃PO₄ → Zn₃(PO₄)₂ + H₂O
We are are going to use simple, solvable algebraic equations to balance this;
aZn(OH)₂ + bH₃PO₄ → cZn₃(PO₄)₂ + dH₂O
a, b,c and d are the number of coefficient that will balance this equation:
Conserving Zn ; a = 3c
O: 2a + 4b = 8c + d
H: 2a + 3b = 2d
P: b = 2c
let c = 1;
a = 3
b = 2
solving for d;
2d = 2(3) + 3(2)
d = 6
3Zn(OH)₂ + 2H₃PO₄ → Zn₃(PO₄)₂ + 6H₂O
