+ Bonded sulfuric acid - 98% H2SO4:
- H2SO4 is a liquid, colorless pure type, specific gravity 1.859 at 0 ° C and 15 ° C in 1837, depending on the impurities it is yellow or gray or brown.
- When cooling the crystals solidified melts at 10.49 ° C. However, the acid can easily supercooled liquid is not solidified at below 0 oC.
- At 30-40 ° C, starts to smoke and the module will generate steam to SO3. Start boiling at 290 ° C and temperatures will rapidly increase until it stops liberate SO3. Hydrates contain 98.3% H2SO4 remaining at 338 oC and Exciting.
- H2SO4 characteristic intense absorption of moisture and thus a good desiccant, H2O vapor pressure over H2SO4 is 0,003mmHg.
- When diluted acid H2SO4 need not be for countries that have the acid in acid in water.
- When heated H2SO4 SO2 and SO3 are part fly off very toxic.
- H2SO4 shot into the skin causes severe burns, shot in the eye may be blind, fall in paper, cloth ... will burn
