Acid Rain

This process occurs at the surface of the buildings or monuments thus acid rain can easily destroy the details on relief work (e g the faces on a statue) but generally does not affect the structural integrity of the building The degree of damage is determined not only by the acidity of the rainwater but also by the amount of water flow that a region of the surface receives Regions

That restarted the evaporation process but filled the solution with floating shards that invariably attached themselves to the crystals I was trying to grow causing them to have surface imperfections and many internal flaws I gave up after two weeks The picture above of a 1-inch long crystal was the best I could do One interesting thing about the shape of this crystal is that the wedge

How to Grow a Salt Crystal Growing sodium chloride salt crystals is a fun and easy science project for kids and a great way to give them their first taste of the science of salt It takes a few days but by growing the crystals you'll see how solutions are made and how the crystalline shapes of salt is formed Take Care! The teacher should demonstrate this experiment which uses boiling

This webpage describes a process that is a relatively simple and safe way to make synthetic potassium nitrate that is quite pure and is perfectly suitable for use as a rocket propellant oxidizer Synthesis Description The synthesis process described here involves a reaction between ammonium nitrate and potassium hydroxide (KOH) that occurs in an aqueous solution Potassium hydroxide is also

A mixture of magnesium ammonium phosphate and ammonium sulphate is obtained as by-product Full Text Field of the invention The present invention relates to a process for making Epsom (MgSO4 7H2O) and Gypsum (CaSO4 2H20) More particularly the present invention relates to an eco-friendly process for the production of epsom and gypsum and utilization of gases released in the process

Generally speaking the chemical resistance of polypropylene and polyethylene is considered superior to that of met-als They are unaffected by most inorganic acids alkalis and aqueous solutions which rapidly corrode metals although some concentrated acids and oxidizing agents can attack them especially at elevated temperatures

Best Method for Hydrochloric Acid Gas by Argox [ Back to the Chemistry Archive ] Background The experienced chemists on this forum will probably scoff at the notion that anything so simple as hydrochloric acid gas (hydrogen chloride or HCl(g)) would require careful explanation as to proper methods set-up and precautions The grim reality is that novice chemists have killed themselves as a

The Effects of Aluminum on the Skin

The Effects of Aluminum on the Skin By Colleen Thurman Alliance/iStock/Getty Images Aluminum in its usual form is not harmful to the skin or any other body part It naturally occurs as part of the earth's crust and is commonly used for many products from soda cans to space shuttles But the ionic and compound forms of aluminum such as those dissolved in water and those often found in
