The neutralization of H3PO4 with KOH is exothermic.
H3PO4(aq)+3KOH(aq)⟶3H2O(l)+K3PO4(aq)+173.2 kJ
If 55.0 mL of 0.207 M H3PO4 is mixed with 55.0 mL of 0.620 M KOH initially at 23.29 °C, predict the final temperature of the solution, assuming its density is 1.13 g/mL and its specific heat is 3.78 J/(g·°C). Assume that the total volume is the sum of the individual volumes.
