Write equations to illustrate whether P4O10(s) is an Arrhenius acid or a base.
P4O10(s) + H2O(l) will eventually have the H3O+ and a negative ion because it is a non-metallic oxide in water.
The Attempt at a Solution
I can think of at least 10 different ways to come up with a H3O+ in the equation, but the answer has a specific answer which is,
P4O10(s) + 6H2O → 4H3PO4(aq)
I don't know why they have 6 H2O's.
I also don't know why they only use one of the 4 H3PO4(aq) for this equation,
H3PO4(aq) + H2O(l) → H3O+(aq) + H2PO4-(aq) .
I can't find anywhere in the chapter that explains how I would know this.
