The reaction between an acid and a base to give a salt and water is called ______.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. neutralisation reaction
A neutralisation reaction is when an acid and a base react to form water and a salt.It Involves the combination of H+ ions and OH- ions to generate water.
- The neutralization of a strong acid and strong base has a pH equal to 7.
- Neutralisation also moves the pH of an alkali down towards seven.
- The reaction between solutions of hydrochloric acid and sodium hydroxide. The overall equation for this reaction is: NaOH + HCl → H2O and NaCl.
- In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
