What is the name of the process when an acid and an alkali react?
Word equations – The reaction between acids and alkalis When an acid reacts with an alkali, a salt and water is produced: acid + alkali → salt + water An example: hydrochloric acid + sodium hydroxide → sodium chloride + water The salt that is produced depends upon which acid and which alkali react. For example: hydrochloric acid + sodium hydroxide = sodium chloride + water If you react an acid and an alkali you always get a salt + water. An alkali is NOT THE OPPOSITE OF AN ACID!!! The opposite of an acid is called a BASE. Answer. a) Neutralisation is the reaction of an acid with neutralisers such as alkalis, carbonates and metal oxides, which produces water and a salt. b) The pH of an acid increases towards 7 in a neutralisation reaction. c) The pH of an alkali decreases towards 7 in a neutralisation reaction. 1  Page. 2  1. 3  2. 4  3. If you use nitric acid you will form a nitrate salt. For example: hydrochloric acid + sodium hydroxide = sodium chloride + water If you react an acid and an alkali you always get a salt + water. An alkali is NOT THE OPPOSITE OF AN ACID!!! The opposite of an acid is called a BASE. For example: hydrochloric acid + sodium hydroxide = sodium chloride + water If you react an acid and an alkali you always get a salt + water. An alkali is NOT THE OPPOSITE OF AN ACID!!! The opposite of an acid is called a BASE. 1. Complete the table (Hint – look for the patterns): Name of alkali Name of acid Sodium hydroxide Potassium hydroxide Hydrochloric acid Sodium chloride Nitric acid Potassium nitrate Sulfuric acid Sodium sulfate Potassium sulfate Salts produced when acids react with alkalis 2. In a neutralisation reaction the pH of the acid moves up towards 7. If an alkali is being used as the neutraliser its pH moves down towards 7. In this video, an acid with a pH of 4 and an alkali with a pH of 11 are used to neutralise each other. The first part is the name of the metal involved in the reaction. This can come from the metal itself, or its compound. For example, the metal in the alkali called sodium hydroxide is sodium.There is only one exception – if ammonia is used to react with the acid, the first part of the name is ammonium.2. In a neutralisation reaction the pH of the acid moves up towards 7. If an alkali is being used as the neutraliser its pH moves down towards 7. In this video, an acid with a pH of 4 and an alkali with a pH of 11 are used to neutralise each other. This forms a solution with a pH of 7. This is because the acid reacts with the alkali to form neutral products. A reaction in which acidity or alkalinity is removed is called neutralisation. A neutralisation involving an acid and a base (or alkali) always produces salt and water.
