# What is the chemical equation for zinc hydroxide solution completely reacts phosphoric acid solution?

Zinc (II) = Zn+2

Hydroxide = OH-

So Zinc Hydroxide = Zn(OH)2

Hydrogen =H+ Phosphate = PO4-3

So Hydrogen Phosphate = H3PO4

So Zn(OH)2 + H3PO4 ---> Zn3(PO4)2 + H2O is the initial equation, but you need to balance it before you can do anything with it, that means that you need an equal amount of each element on each side of the equation.

3 Zn(OH)2 + 2 H3PO4 ---> Zn3(PO4)2 + 6H2O

Its easy to check the equation to make sure its balanced, just count your elements on each side of the arrow

3Zn + 12H + 6O + 2PO4 on each side of the equation, and its balanced. Wiki User

Phosphoric Acid dissociates to give off 3H+ ions, meaning that one mole of Phosphoric acid reacts with three mols of sodium hydroxide. Using the equation n = c x v n = 0.1 x 0.05 =0.005 mols of OH ions in the solution therefore there are 0.005/3 = 0.00167 So the volume of phosphoric acid - v = n/c v = 0.00167/0.2 v = 0.00835 l = 8.4ml of Phosphoric Acid reacts completely with Sodium hydroxide
