Question

The formula of microcosmic salt and the product obtained by heating it is

• A. $Na \left( NH _{4}\right) PO _{4} ; NaPO _{3}$
• B. $Na \left( NH _{4}\right)_{2} HPO _{4} ; NaPO _{3}$
• C. $Na \left( NH _{4}\right) HPO _{4} ; NaPO _{4}$
• D. $Na \left( NH _{4}\right) HPO _{4} ; NaPO _{3}$

Answer 1

Answer: (D)

$Na \left( NH _{4}\right) HPO _{4} ; NaPO _{3}$

Answer 2

Microcosmic salt is Na(NH 4 )HPO. ${Na(NH4 )HPO4 ->[?] NaPO3 + H2O + NH3}$ It is prepared by : ${NH4Cl + Na2HPO 4 + 4H2O -> Na(NH4)HPO4. 4H2O + NaCl}$
