Question

All salts are:
A. Strong electrolytes
B. Weak electrolytes
C. Non electrolytes
D. Either weak or strong electrolytes

Answer 1

Hint: Salts are chemical species that consist of ionic bonds between the cations and anions. Salts are composed of a related number of positively charged ions and negatively charged ions and therefore the species is electrically neutral or they have total no net charge on them.

Complete Step by step answer: salts are composed of ionic bonds between the negative and positive charge ions. These ions can be inorganic ion or organic ions and monatomic or polyatomic. Inorganic ions like fluoride ions, organic like acetate ions, monoatomic like oxide ion, polyatomic like phosphate ions.
Salts when dissolved in water, if they produce hydroxide ion $O{H^ - }$ are known as basic salt. If they produce acidic solutions then they are called acid salt. There are some salts which do not produce basic nor acid salt then they are called neutral salts.
Salt or electrolyte can be strong or weak. Strong salts or strong electrolytes salts are the chemical salts composed of strong electrolytes. When dissolved in water, these compounds dissociate completely in the water and give corresponding ions in the solution. Example- sodium nitrate $NaN{O_3}$
$NaN{O_3} \to N{a^ + } + N{O_3}^ - $
Weal salts or weak electrolyte salts are composed of weak electrolytes. When they dissolve in water, they partially dissociate in the solution. Example- sodium acetate $C{H_3}COONa$
$C{H_3}COONa\underset{{}}{\overset{{}}{\longleftrightarrow}}C{H_3}CO{O^ - } + N{a^ + }$

Therefore salts are either weak or strong electrolytes. So the correct option is D.

Note: Strong electrolytes are generally odorless and also non-volatile, while the weak electrolytes have odor similar to those acid and base from which they are derived like sodium acetate smell similar to acetic acid.
