Welcome to the Chemistry area of the site, here you can browse the different catagories we have and have a look at the different pages available.
The blast furnace is used to extract iron from haematite. Carbon monoxide is the reducing agent and heated air is added to move the reaction. The products from the blast furnace are molten slag and molten airs.
Molecules have different shapes, we look at the simple shapes of covalent molecules and the bond angles, including the well-known tetrahedral. States of matter, and different types of crystals.
Alcohols have an C-OH functional group. They can be primary, secondary or tertiary. Ethanol can be manufactured by fermentation (drinks) or from ethene (industrial). Alcohols can be oxidized to an aldehyde then carboxylic acid.
Acid and bases are defined in terms of protons in this definitions; giving rise the the value of pH. The ionic product of water is Kw can be used in calculations and Ka for weak dissociation.
There has been some major rearranging of the Chemistry section, there is a singal tier of 5 catagories that should make more sense. Pages that have been moved or merged have got redirections so you know where to go for the content.
Appologies for this, but hopefully it will make the site easier to use.
