Dear kirti98sharma@yahoo.com

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

We cannot entertain more than 2 questions in a single query. 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.
Answer to your first question is given below:
1.How can we identify the pH value of salt by just seeing the chemical formula ?
We cannot identify exact pH value of salt by just seeing the chemical formula but we can identify the nature of the salt formed depending on the strength of acids and bases used.
There are six kinds of salts.
1. Normal salt
2. Acidic salt
3.Basic salt
4.Double salt
5.Mixed salt
6.Complex salt
pH value can be determined by taking an aqueous solution of the salt and then dipping a pH paper.
