can anyone point out what the reaction wud be, its appeared in my past paper but cant find anywhere in books (or on the syllabus) but that's typical of the chemistry exams these days.

Anyways thanks :smile:


phosphorus (V) oxide is an acidic oxide and sodium hydroxide is a base...

acid + base --> salt + water

the question is testing your knowledge of oxides.
