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)
