Question

Formula of microcosmic salt is

• A. $Na _{2} HPO _{4}$
• B. $Na \left( NH _{4}\right) HPO _{4}$
• C. $K _{2} HPO _{4}$
• D. $Na _{2} PO _{4} \cdot K _{2} PO _{4}$

Answer 1

Answer: (B)

$Na \left( NH _{4}\right) HPO _{4}$

Answer 2

Microcosmic salt formula is $\left( NH _{4}\right) NaHPO _{4}$. It is left behind in the residues after extracting the urea from dried urine crystals with alcohol. In the mineral form, microcosmic salt is called stercorite.
