Iodine clock reaction - Wikipedia

The iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886. The iodine clock reaction exists in several variations, which each involve iodine species (iodide ion, free iodine, or iodate ion) and redox reagents in the presence of starch.Two colourless solutions are mixed and at first

Pseudo First Order Reaction: Order of reaction,

Sometimes adults 'fake' being younger when they're actually way older. Isn't it? Did you know we can 'fake' in chemistry as well? Yes, a reaction whose order of reaction is actually more than one can 'fake' being a first order reaction. This type of reaction is known as a pseudo first order reaction. Let's understand what a pseudo first order reaction is and how it 'fakes

An Introduction to Combustion (Burning)

A combustion reaction is a major class of chemical reactions, commonly referred to as "burning." In the most general sense, combustion involves a reaction between any combustible material and an oxidizer to form an oxidized product. It usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water. Good signs that you're dealing with a combustion reaction include the
