Question

Stoichiometric ratio of sodium dihydrogen orthophosphate and sodium hydrogen orthophosphate required for synthesis of Na5P3O10 is :-

a) 1:5:3
b)3:1:5
c)1:1
d)2:3

Answer 1

Welcome Jiya,

◆ Answer - (1)

NaH2PO4 : Na2HPO4 = 1.5 : 3

● Explanation -

Reaction of sodium dihydrogen orthophosphate and sodium hydrogen orthophosphate to form sodium triphosphate is as follows -

NaH2PO4 + 2 Na2HPO4 --> Na5P3O10 + 2 H2O

As we can see stoichiometric ratio of reactants is

NaH2PO4 : Na2HPO4 = 1 : 2 = 1.5 : 3

Thanks dear. Hope this helps you..
