Phosphoric Acid
Phosphoric acid is classified as weak acid as Phosphoric acid undergoes partial dissociation in water solution as it does not fully dissociate into H+ (H3O+) and the dihydrogen phosphate ion when dissolved in water and producing a low concentration of hydrogen ions . So, Phosphoric acid is a weak acid .
Phosphoric acid chemical formula is H ₃PO ₄. Orthophosphoric acid refers to phosphoric acid.

Phosphoric Acid is used as fertilizer ::: It is important, what the soil in your yard (field). If the pH is 6,5 -7, then everything is fine. But for acidic soil if pH < 6, avoid uses of phosphoric acid will increase the acidication of soil, which can damage most crops. In this case it is possible to add sodium carbonate or potassium carbonate.
Apply the H3PO4 can be a fertilizer of different cultures. If the acid is concentrated, the dosage should be no more than 18 g per 10 liters of water.
GENERAL GUIDE LINE :
When fertilizer input with irrigation water, maximum allowable concentration of nutrients in the water should not exceed to 0.5% of Nitrogen fertilizer, for Phosphate - 2% and Potash - 3%. For complex solutions content of nutrients - less than 1%.
Pure phosphoric acid is colorless, odorless and has sour odor.
Phosphoric acid is Soluble in water and ethanol. Easily absorb moisture. Easy to be crystallized under cold condition for long time.
Phosphoric Acid is Corrosive. Should be stored in closed containers.
