PHOSPHORUS PENTOXIDE ACIDIFIES WATER<br />
(2 of 5 - Variations Available)<br />
Methyl Red  Indicator with P4O10 (s)  and Water<br />
P4O10(s) is stirred into the water forming phosphoric acid (indicator shifts to red) and generating enough heat to create steam in an exothermic reaction. P4O10(s) + 6 H2O(l) --> 4 H3PO4(aq)
