Title: Name of chemical used in cleaning Lab glasswares
Star - August 1, 2005 11:19 PM (GMT)
Tanong ko lng lalo na sa mga Chem grad, ano nga yung tawag sa gamit nating chemical/s na pang linis sa glaswares sa Lab? I can't remeber the name pero parang mixture lng sya ng acid (H2SO4, HNO3)???
tnx!

nadumduman ko sng nag fieldtrip kmi sng high school sa isa ka softdrink company, Sodium Hydroxide(NaOH) solution nga mainit ang gamit nila panghugas sng bottles.

Synonyms: caustic soda, soda lye, lye, white caustic, aetznatron, ascarite, Collo-Grillrein, Collo-Tapetta, sodium hydrate, fotofoil etchant, NAOH, STCC 4935235, sodium hydroxide pellets, Lewis red devil lye
Molecular formula: NaOH
Stability: Stable. Incompatible with a wide variety of materials including many metals, ammonium compounds, cyanides, acids, nitro compounds, phenols, combustible organics. Hygroscopic.

i did not imply that Sodium Hydroxide is not the correct chemical. i just posted the Health Hazard of that chemical (if ever they would use it). :hmmm:
