Can anyone tell how we can identify which acids and bases reacts to form the given salts...??
And how do we classify if the salt is either acid or basic...?? Also how can we say if the the given acid or base is strong or weak...??

Answer:
Identifying Acids, Bases and Salts
Once you have learned the concept of electrolytes dissociating in water to form ions and can write chemical equations for that process, the task of identifying acids, bases and salts is relatively easy.
Starting with the formula of an electrolyte, first identify the postive and negative ions that will be formed when the electrolyte dissolves in water. If
the positive ion is H
+
the compound is an acid. If the negative ion is OH
-
the compound is a base. If neither of the above is the case the compound is a salt. Note that this all depends on the compound being an electrolyte (either weak or strong).
Like if HX gives H+ ions and X in water , it is an acid..
If YOH gives Y and OH- ions in water it is a base.
If YX give different ions other than H+ and OH- then it is a salt..

Hydrolysis of Salts | Salt Hydrolysis, pH of a Salt Solution, Types of Salts
Salt is an essential substance for the human body. Salt is made from an acid and a base; it can react with water and produce acidic, basic, or neutral solutions. In this lesson, we will know about salt hydrolysis and how to determine whether the salt is acidic, basic, or neutral, and ph of their solutions.
Hydrolysis Of Salt
The hydrolysis reaction is a reaction involving the breaking of a bond in a molecule using water. The reaction primarily occurs between an ion and water molecules and mostly changes the pH of a solution. Primarily, in chemistry, there are three types of hydrolysis: salt hydrolysis, acid hydrolysis, and base hydrolysis.
Salt is an ionic compound prepared from the reaction of an acid and a base solution. Salts help the body by forming solutions that are acidic, basic, or neutral. Depending on the situation, your body needs different types of solutions to function and maintain its natural processes. Let's start with some key definitions before jumping into the topic.
An ion is an atom with an electrical charge that is made from losing or gaining electrons.
A hydroxide ion (OH-) is made when the conjugate base accepts a proton from water and causes the aqueous solution to become basic
A conjugate acid is a substance made when the base accepts a hydrogen ion.
A conjugate base is a substance made when the acid donates a hydrogen ion.
A hydronium ion (H3O+) is formed when the conjugate acid donates a proton to water, causing it to become the acidic solution.
Those were the key terms to learn and understand salt hydrolysis, which can be simply explained that when a salt completely dissociates in water and its anion or cation reacts with the water to form hydroxide ions or hydronium ions that affect the pH of the solution.
