- This is a poison. Do not ingest
- H3BO3 (sometimes written B(OH)3)
- Solubility in water 2.52 g/100 mL (0 °C), 4.72 g/100 mL (20 °C), 5.7 g/100 mL (25 °C), 19.10 g/100 mL (80 °C), 27.53 g/100 mL (100 °C)
- This is a very strong flux but its solubility is lower than most other compounds mentions here. I have read (I think) that when mixed with borax the solubility goes up. This is counter-intuitive. They have common ions and normally such solutions do not increase but decrease solubilities.
- Boric Acid reacts with many bases in the studio such as soda ash, sodium bicarbonate, related potassium and lithium compounds and some soluble colorants. I beleive that it reacts directly with lithium carbonate to form lithium borate. With the bases expect the evolution of gases. It can bubble over or blow up a closed container. I read somewhere that under pressure in solution it reacts with calcium to form calcium borates. I do not know which calcium borate it form. I believe that his is the reaction used at the CadyCal? mine. I could completely be wrong.
Boric Acid is used as an insecticide.
There is an insoluble calcium magnesium borate.
