Hint: To solve this we should know about:
Acid: An acid is a molecule or ion that may donate or accept a proton.
Base: A base is a chemical that reacts with hydrogen ions to neutralize an acid.
To solve this question we go through the properties of acid and base when it reacts with metal as well as we take examples to understand what will be the output or resultant form after the reaction.
Complete answer:
Reaction with metal:
However, not all metals react to acids in the same manner. When an acid combines with a metal, it produces salt and hydrogen gas.
Example:
Hydrochloric acid combines with zinc powder to produce gas and zinc chloride.
The amount of salt created is determined by the reaction of acid and metal.
Metals react with dilute hydrochloric acid to generate chloride salts and hydrogen, which is then released as bubbles. In the case of magnesium, the rate of bubble formation was the fastest.
The reaction was also the exothermic reaction and the reactivity decreases in the order
Reaction with base:
The foundation has a harsh flavor and is slick to the touch.
An alkali is a base that dissolves in water. Salts are formed when such substances react chemically with acids. On red litmus paper, bases are known to become blue.
Hydrogen gas is formed when a base reacts with a metal. When a burning candle is brought close to the test tube's mouth, it makes a popping sound.
Metal + Base → Hydrogen + Salt
Examples of base reactions with metals
When sodium hydroxide interacts with zinc metal, hydrogen gas and sodium zincate are produced.
Sodium aluminate and hydrogen gas are formed when sodium hydroxide reacts with aluminium metal.
So, we can say that almost all metals react with acid and base to form salt and hydrogen.
Note:
When we solve this question we should keep in mind what will be the reactant as well as the condition or environment in which it will react. When we will write a chemical equation that should be balanced it means the number of elements on L.H.S. will equal the element on the right hand side. It is known as a balanced chemical equation.
