Explanation:
Detailed explanation-1: -Acids are substances that provide hydrogen ions (H+) and lower pH, whereas bases provide hydroxide ions (OH–) and raise pH.
Detailed explanation-2: -If we mix equal amounts of an acid and a base then two chemicals essentially cancel out each other and produce salt and water. Mixing equal amounts of a strong acid with strong base results in a neutral solution whose pH value remains 7 and this type of reactions are known as neutralization reactions.
Detailed explanation-3: -A neutralization reaction is when an acid and a base react to form water and a salt and 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.
