What is a neutralisation reaction? - BBC Bitesize

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. WebEthanoic acid 0.1 mol/dm 3; Hydrochloric acid 0.1 mol/dm 3; Method. Using a measuring cylinder, measure 5 cm 3 of hydrochloric acid and add to a test-tube. Repeat step 1 with ethanoic acid into a separate test-tube. Add 5 drops of Universal Indicator to each test-tube and record the pH, or use a pH meter to record the pH. try now truck game

Reactions of acids with metals - Acids and alkalis - BBC Bitesize

Webalcohol + carboxylic acid → ester + water For example: ethanol + ethanoic acid → ethyl ethanoate + water Weak and strong acids - Higher Carboxylic acids are weak acids. This means that... 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.
