write the meaning and examples of strong and weak acid, base and alkali
Answers
Answer:
An acid which dissociates completely or almost completely in water are strong acids.Eg: chloric acid, nitric acid, sulfuric acid, hydrochloric acid ,etc. and an acid that dissociates only partially when dissolved in water are weak acids. Eg: formic acid, oxalic acid, acetic acid.
A base is a substance that can accept a hydrogen ion (H+) from another substance. A chemical can accept a proton if it has a negative charge, or if the molecule has an electronegative atom like oxygen, nitrogen, or chlorine that is rich in electrons. Like acids, some bases are strong and others are weak.
Alkali is a compound with particular chemical properties including turning litmus blue and neutralizing or effervescing with acids; typically, a caustic or corrosive substance of this kind such as lime or soda.
Explanation:
strong acid:-
the acids that give more H30+ ions are said to be strong acids
examples:- hydrochloric acid,perchloric acid ,nitric acid ,sulfuric acid ,
weak acids :-
the acids that give fewer H3o+ ions are said to be weak acid
examples:-acetic acid,vinegar
base:-
any substance that has bitter taste and soapy in nature that turns red litmus to blue is called a base
examples:-sugar ,baking soda, soap and bath products
alkali:-
an alkali is a base that dissolves in water
examples:- sodium hydroxide,potassium hydroxide, magnesium hydroxide
