WebIndicators are used to determine whether a solution is acidic or alkaline. Acids react with metals, bases and carbonates to produce salts. Neutralisation is the reaction between an acid and a base. WebCarboxylic acids with branches can also be named following the rules. The longest carbon chain in the molecule below contains four carbon atoms. As the carbon of the carboxyl group is the first of the chain, then both branches are on the third carbon. This molecule is therefore called 3,3-dimethylbutanoic acid. Reactions of carboxylic acids

WebEsters are formed by the condensation reaction between an alcohol and a carboxylic acid. This is known as esterification. In a condensation reaction, two molecules join and produce a larger molecule whilst eliminating a small molecule. During esterification this small molecule is water. Esters have characteristic smells and are insoluble in water. WebAcids and alkalis Key points An acid and alkali will neutralise each other and produce a salt and water. This is called a neutralisation reaction. The name of the salt produced can be worked... WebYou can do this reaction at home but make sure you don’t get any of the chemicals in your eyes.
