  • Gas of rotten eggs

    If you happen to break a rotten egg, then you know the smell of hydrogen sulfide, because the stench of the spoiled egg depends on of its presence in rotting protein substances.

  • Use of diamonds

    Diamond is a crystalline modification of pure carbon formed in the deep interior of the Earth, in the upper mantle at depths of more than 80-100 kilometers, at exceptionally high pressure and temperature. It is the most precious stone, the hardest and most wear-resistant mineral, the most...

  • Chemical Safety

    People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...

    In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.

  • Creating Malachite egg

    One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but...

Sulfuric Acid

H2SO4: colorless, oily liquid, boiling point 330C. A 96 percent solution is used in the laboratory.

Fire Hazard: This is a very powerful, acidic oxidizer which can Ignite or even explode on contact with many materials, i.e. acetic acid ,acetone+ HNOs, alcohols, + H202, NH4OH, HCL, NaOH, and others.

Sulfuric acid has a wide range of uses and plays a part in the production of nearly all manufactured goods.
