10 FACTS YOUR CHEMISTRY TEACHER MAY NEVER TELL YOU.

Image
In most cases, you shouldn't and must not expect your Chemistry teacher to teach you all you need to know in chemistry.  Most times, due to limited time and resources, The teacher will only teach you based on the syllabus and will not bother to explain some mysterious facts in chemistry to you.  Worst enough, some teachers strictly hide these facts because they just want to be above their students in terms of knowledge. Here are ten facts your Chemistry teacher may never tell you. 1. The word ALKALI is derived from the Arabic word ALQILI which means "plant ash." 2. Alkaline 'earth' metals are called so because the early alchemists believed that any element whose compounds are insoluble in 'water', unchanged by ' fire ' and unburnt in ' air ' is ' earth '. For example, Calcium has the compound Calcium oxide which possesses these properties. 3. ' Aldehyde ' literally mean ALcohol DEHYDrogEnated . 4. The word Pa...

Why Does Your Roof Turns Brown?- Adebola Daniel

By: Adebola Daniel     Flying an aeroplane across Ibadan city, a pilot may begin to wonder about the heat, the dust and most especially the brown roofs on the dilapidated buildings. Children waving on the streets, waiting for gravity to pull him down. What really is the cause of the brown roofs? The answer is just ELECTROCHEMISTRY IN ACTION!     The gradual deterioration of metals by an electrochemical process is termed CORROSION. The shiny roofing sheets on your house is made of Iron which corrodes in the presence of oxygen and water. The corrosion of Iron is specifically called RUSTING. The reaction occuring is very complex, however, the main steps are explained below.      In the presence of oxygen and water, a region of the Iron sheet acts as anode (let the reader understand) where oxidation occurs. The electrons released are used to reduce atmospheric oxygen to water in another region of the metal which acts as the cathode....

CHEMISTRY SPEAKS: Why Do You Cry While Cutting Onions?- Daniel Adebola

On a very special day, probably your birthday, have you ever wondered why your joy turns to tears in the kitchen? You've decided to fry your eggs with slices of onions, but cutting the onions make you cry. Then you ask yourself; Why do onions make me cry? The answer is just CHEMISTRY IN ACTION.  Onion as a vegetable, has a defense mechanism. It produces an irritating chemical substance known as Propanethial-S-oxide which prevents the onions from being eaten by pests. This substance is what is known as LACHRYMATORY FACTOR   When  you cut an onion, this sulphur gas evaporates and rises to your eyes. It dissolved in the water covering the surface of your eyes to form SULFENIC ACID. However, since the amount of this acid produced is relatively small, it's effect is usually not harmful but only irritating. The  Sulfenic acid irritates your lachrymal gland (also called tear gland) which produces tears which is actually meant to wash away the Sulfenic acid. However, to pre...
