Question

Which of the following is a complex salt?
A. Fischer salt
B. Mohr's salt
C. Glauber's salt
D. Microcosmic salt

Answer 1

Salt is an ionic compound that contains a cation (base) and an anion (acid).
It is present in large quantities in seawater, where it is the main mineral constituent. Salt is essential for animal life and saltiness is one of the basic human tastes. Salt is an ionic compound that has a cation other than ${H^ + }$ and an anion other than $O{H^ - }$ and is obtained along with water in the neutralization reaction between acids and bases.

Complete step by step answer:
Complex salt: A complex salt is a salt that contains one or more complex ions—ions with metal centers and different molecules attached.
Mohr's salt is Ammonium iron (II) sulfate, is the inorganic compound with the formula,${(N{H_4})_2}Fe{(S{O_4})_2}.6{H_2}O$.
Containing two different cations, $F{e^{2 + }}$ and$NH_4^ +$, it is classified as a double salt of ferrous sulphate and ammonium sulphate.
Microcosmic salt is a salt found in urine with the formula $Na(N{H_4})HP{O_4}$ which is not a complex salt.
Glauber's salt is $N{a_2}S{O_4}.10{H_2}O$.
Fischer salt is a complex compound having a formula ${K_3}[Co{(N{O_2})_6}]$.

So, the correct answer is Option A.

Additional information:
Hydrolysis of salt refers to the reaction of salt with water. It is the reverse of a neutralization reaction. In this reaction, when salt undergoes reaction with water, the constituent acid and base are formed as products. In hydrolysis, the salt dissociates to form ions, completely or partially depending upon the solubility product of that salt.

Note: The compound’s sodium chloride has very different properties from the elements sodium and chlorine.
Saltwater contains ions and is a fairly good conductor of electricity.
This electrostatic force of attraction holds the ions together and a chemical bond is said to form between them.
