Q. Stoichiometric ratio of sodium dihydrogen orthophosphate and sodium hydrogen orthophosphate required for synthesis of ${Na}_{5}P_{3}O_{11}$ is
A) 1.5 : 3
B) 3 : 1.5
C) 1 : 1
D) 2 : 3
Explanation
(b)
$2Na_{2}HPO_{4} + NaH_{2}PO_{4} + 2\left( NH_{2} \right)_{2}CO \rightarrow Na_{5}P_{3}O_{10} + 4NH_{3} + 2CO_{2}$
Hence, the stoichoimetric ratio of sodium dihydrogen orthophosphate and sodium hydrogen orthophosphate is 2 : 1 or 3 : 1.5
