Dear 381947642190298@facebook.com

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.

We have answered your first 2 queries.
 

1. Carbonic acid is a diprotic acid. After neautralisation it is still consist of one H that can be displaced. On the other hand in HCl there is no more replaceable H. Due to this carbonic acid gives an acid salt but HCl does not give the same.

 

2. Both hydrochloric acid as well as acetic acid is acids; however they differ in their strength. The strength of an acid is determined by the extent of its ionisation in aqueous solution. HCl ionises 100% in aqueous solution while highly concentrated acetic acid ionises upto 5%. Due to this HCl is stronger than conc. acetic acid.
