Question

HNO3 is a strong acid but CH3COOH is not. Why?

Answer 1

Explanation:

HNO3. CH3COOH is a weak acid because it ionises only partially in aqueous solution and produce ions as well as molecules.

Answer 2

Explanation:

Well the answer is depended on your grade but I will try to answer in a way that will be relevant to all the grades below junior year high school

Note that this answer is completely based on the strength of an acid

CH3COOH is an Organic acid which automatically makes it weaker than most if the acids known to humans (to be specific, weaker than inorganic acids). Being an organic acid its concentration of H+ protons is less compared to stronger acids. Now to answer this question ket us first understand what is a weak acid? Well, according to the grade level of this answer, any acid that undergoes partial dissociation in aqueous solutions, producing low concentration of H+ ions is weak, which is exactly what acetic acid does.

HNO3 on the other hand is an inorganic acid which already gives it an advantage over Acetic acid on the basis of strength. Lets us now understand what is a strong acid, well a strong acid is an acid that undergoes complete dissociation in an aqueous solution producing a high concentration of H+ or H3O+ protons, and nitric acid does exactly that.

Hence, Nitric Acid [HNO3] is a stronger acid as compared to Acetic Acid [CH3COOH].

Note:- this was an explanation for your question so I would suggest not to copy it but yo compress it in your own words to 1) understand the concept better and 2) give a better and more "to the point" answer

Thanks
