When tri-sodium phosphate is used, 98% of the salt will hydrolyse to di-sodium phosphate and sodium hydroxide according to the following reaction. 3 4 2 + → 2 4 + Na PO H O Na HPO NaOH (8) Thus one mole tri-sodium phosphate will increase boiler water pH equivalent to one mole sodium hydroxide if boiler water pH is in the range of 9 to 10.0.
