A) \[{{K}_{2}}S{{O}_{4}}.A{{l}_{2}}{{(S{{O}_{4}})}_{3}}.24{{H}_{2}}O\]
B) \[FeS{{O}_{4}}.{{(N{{H}_{4}})}_{2}}S{{O}_{4}}.6{{H}_{2}}O\]
C) \[Na(N{{H}_{4}})HP{{O}_{4}}.4{{H}_{2}}O\]
D) \[CaS{{O}_{4}}2{{H}_{2}}O\]
Correct Answer: C
Solution :
\[\underset{\text{Micro cosmic salt}}{\mathop{Na(N{{H}_{4}})HP{{O}_{4}}}}\,\xrightarrow{\Delta }\underset{\text{Sodium meta phosphate (transparent)}}{\mathop{NaP{{O}_{3}}+N{{H}_{3}}+{{H}_{2}}O}}\,\]You need to login to perform this action.
