Question

which basic salt is prepared by using strong base and weak acid​

Answer 1

$\huge\bold\pink{answer}$

When weak acids and bases react, the relative strength of the conjugated acid-base pair in the salt determines the pH of its solutions. The salt, or its solution, so formed can be acidic, neutral or basic. A salt formed between a strong acid and a weak base is an acid salt, for example NH4Cl.

Answer 2

Answer:

When weak acids and bases react, the relative strength of the conjugated acid-base pair in the salt determines the pH of its solutions. The salt, or its solution, so formed can be acidic, neutral or basic. A salt formed between a strong acid and a weak base is an acid salt, for example NH4Cl .

Salts that Produce Basic Solutions

There are several varieties of salts, and in this section we will consider basic salts. What makes a basic salt basic? It is due to the fact that the anion in the salt is the conjugate base of a weak acid. For a generalized anion B–, the net ionic reaction is:

An example of a basic salt is sodium bicarbonate, NaHCO3. The bicarbonate ion is the conjugate base of carbonic acid, a weak acid. Therefore, it reacts with water in the following fashion:

Because it is capable of deprotonating water and yielding a basic solution, sodium bicarbonate is a basic salt.

Other examples of basic salts include:

Calcium carbonate (CaCO3)

Sodium acetate (NaOOCCH3)

Potassium cyanide (KCN)

Sodium sulfide (Na2S)

Notice that for all of these examples, the anion is the conjugate base of a weak acid (carbonic acid, bisulfate (second dissociation step of sulfuric acid), acetic acid, hydrocyanic acid, hydrogen sulfide).
