Which of the following oxoacids of phosphorus is used as a flame retardant and in the production of polyphosphate compounds?
Phosphoric acid
Pyrophosphoric acid
Hypophosphorous acid
Orthophosphoric acid
Correct Option D
Orthophosphoric acid is used as a flame retardant and in the production of polyphosphate compounds due to its ability to form strong bonds with metal ions. Hence option D is the correct answer.
Option (A) is incorrect because orthophosphoric acid is used as a flame retardant and in the production of polyphosphate compounds due to its ability to form strong bonds with metal ions. Hence option A is incorrect.
Option (B) is incorrect because orthophosphoric acid is used as a flame retardant and in the production of polyphosphate compounds due to its ability to form strong bonds with metal ions. Hence option B is incorrect.
Option (C) is incorrect because orthophosphoric acid is used as a flame retardant and in the production of polyphosphate compounds due to its ability to form strong bonds with metal ions. Hence option C is incorrect.
