Acid-base titration is a method used to determine the concentration (quantitative analysis) of an acid or base. Despite the complicated sounding name (at least for most Form 4 students in Malaysia), it is just a simple neutralisation process based on the principle where the moles of acids will eventually be equal with the moles of [...]

Neutralisation is the name given for a chemical reaction involving an acid and base where they interact and ends with the formation of salt. In it, the base “cancels out” the acid in the reaction. Understanding the definition of this is important to identify the neutralisation process which occurs regularly but goes unnoticed by most [...]

If we are talking about opposites in chemistry, there can not be any more opposites than acid and alkali. Acids are the chemical opposites of bases. This is (partly) due to their where acids donates a hydrogen ion to another compound called base, hence they are chemically opposite. Of course there are other differences between [...]
