boric acid

 [bor´ik]
a mild acid used as a buffer. It was formerly used as a household antiseptic for treating minor irritations of the skin and eyes. Because the powder is highly poisonous when taken internally, and since other antiseptics are more effective, boric acid is no longer recommended. Boric acid ointment (for external use only) occasionally helps in cases of mild skin irritations and keeps gauze dressing from sticking to a wound. It is also used as a pesticide to kill ants and cockroaches.

It is clear from the Tables 1, 2, 3 and 4 that the quantities of acids namely; phosphoric acid, oxalic acid, acetic acid and formic acid used per litre of liming effluent to settle the SS are 13 mL, 8 mL, 15 mL & 15 mL, 15 g, 12 g, 15 g & 20 g, 25 mL, 15 mL, 25 mL, & 27 mL, 13 mL, 11 mL, 13 mL, & 14.9 mL, respectively, which is quite negligible quantity with the exception of boric acid which is 550 g, 530 g, 350g and 550 g accordingly and obviously higher than the preceding acids.
