Question
The neutralization of H₂PO4 with KOH is exothermic.
H₂PO4 (aq) + 3 KOH(aq) → 3 H₂O(1) + K3PO4 (aq) + 173.2 kJ
If 70.0 mL of 0.233 M H₂PO4 is mixed with 70.0 mL of 0.700 M KOH initially at 21.70 °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.
