Question

Classify these salts as acidic, basic, or neutral. Acidic Basic Neutral NH4ClO4 NaF LiNO3 KCI K2CO3

Answer 1

General guidance

Concepts and reason

The concept used to solve this problem is based hydrolysis of the salt and their behavior in the aqueous solution. The salt gets dissociated in the aqueous medium and form bond with the hydrogen ion and the hydroxyl ion present in the water.

Fundamentals

The salt gets dissociated in an anion and a cation. The anion reacts with the hydrogen ion present in the water. Whereas, the cation reacts with the hydroxyl ion present in the solution. The determination of the type of the salt is done by studying the overall pH (potential of hydrogen) of the salt solution.

Step-by-step

Step 1 of 3

The salt ${\\rm{N}}{{\\rm{H}}_{\\rm{4}}}{\\rm{Cl}}{{\\rm{O}}_{\\rm{4}}}$ dissociates as follows.

It is an acidic salt.

Explanation

The salts get dissociated in an anion and a cation. In the aqueous medium, the salt ${\\rm{N}}{{\\rm{H}}_{\\rm{4}}}{\\rm{Cl}}{{\\rm{O}}_{\\rm{4}}}$ gets dissociated into ${\\rm{HCl}}{{\\rm{O}}_{{\\rm{4\\;\\;}}}}$ and${\\rm{N}}{{\\rm{H}}_{\\rm{4}}}{\\rm{OH}}$. The ${\\rm{N}}{{\\rm{H}}_{\\rm{4}}}{\\rm{Cl}}{{\\rm{O}}_{\\rm{4}}}$molecule get dissociated in a weak base and the strong. The overall pH of the solution is acidic.

Step 2 of 3

The salt ${\\rm{NaF}}$ dissociates as follows.

It is a basic salt.

The salt ${{\\rm{K}}_2}{\\rm{C}}{{\\rm{O}}_3}$ dissociates as follows.

It is a basic salt.

Explanation

In the aqueous medium, the salt ${\\rm{NaF}}$ gets dissociated into ${\\rm{NaOH}}$ and${\\rm{HF}}$. The salt ${{\\rm{K}}_{\\rm{2}}}{\\rm{C}}{{\\rm{O}}_{\\rm{3}}}$ gets dissociated into ${\\rm{KOH}}$and${{\\rm{H}}_{\\rm{2}}}{\\rm{C}}{{\\rm{O}}_{\\rm{3}}}$. The salts${\\rm{NaF}}$and ${{\\rm{K}}_{\\rm{2}}}{\\rm{C}}{{\\rm{O}}_{\\rm{3}}}$ gets dissociated into a weak acid and a strong base. The overall pH of the solution represents basic pH.

Step 3 of 3

The salt ${\\rm{LiN}}{{\\rm{O}}_3}$ dissociates as follows.

It is a neutral salt.

The salt ${\\rm{KCl}}$ dissociates as follows.

It is a neutral salt.

Acidic salts Basic salts Neutral salts NH4CIO4 NaF L\u0130NO3 K2CO3 KCI

In the aqueous medium, the salt ${\\rm{LiN}}{{\\rm{O}}_3}$gets dissociated into ${\\rm{LiOH}}$ and${\\rm{HN}}{{\\rm{O}}_{\\rm{3}}}$. The salt ${\\rm{KCl}}$ gets dissociated into ${\\rm{KOH}}$and${\\rm{HCl}}$_. The salts ${\\rm{LiN}}{{\\rm{O}}_3}$ and ${\\rm{KCl}}$ are dissociated into strong acid and strong base. The overall pH of the solution is neutral.

The stronger molecules dominates the overall pH of the solution. The strong base or the strong acids masks the effect of the weak molecules (weak acids and weak base). In the presence of the strong bases and the strong acids, the effect of the acids and the bases is masked and the overall pH comes out to be neutral.
