In a constant-pressure calorimeter 700ml of 0310 m baoh2, Ask an Expert

Academics

In a constant-pressure calorimeter 70.0mL of 0.310 M Ba(OH)2 was added to 70.0mL of 0.620 M HCl. The reaction reasons the temperature of the solution to rise from 21.68°C to 25.90°C. If the solution has the same density as well as specific heat as water, what is PH for this reaction (per mole of H2O produced)? Presume that the total volume is the sum of the individual volumes.
