# Enthalpy of h2so4

Discussion: The heat released in this demonstration is a result of the hydration of the various ions formed upon dissociation of the acid: H2SO 4 → HSO 4 1-+ H 1+ K 1 >> 1 HSO 4 1-↔ SO 4 2-+ H 1+ K 2 0.012 (25 oC) The heats of reaction for the described dilutions have been calculated by Shakhashiri.

Enthalpy change per mole of H2SO4 in reaction. write Balance equation. Chemistry Help asap!Whole problem below? A 90.0 ml sample of 1.00M NaOH is mixed with 45.0 ml of 1.00M H2SO4 in a large Styrofoam coffee cup; the cup is fitted with a lid through which passes a calibrated thermometer. Apr 10, 2014 · In the neutralization of H2SO4, 2 moles of water are formed, while in the neutralization of HCl, only 1 mole is formed. Thus, the enthalpy of neutralization of H2SO4 will be twice that of HCl. Since the neutralization of H3PO4 will form 3 moles of H2O, the enthalpy of neutralization for H3PO4 should be about:-114.2 kJ/mol X 1.5 = -171.3 kJ/mol
May 31, 2018 · Calculate the heat of neutralization using the fomula Q = mcΔT, where "Q" is the heat of neutralization, "m" is the mass of your acid, "c" is the specific heat capacity for aqueous solutions, 4.1814 Joules(grams x °C), and "ΔT" is the change in temperature you measured using your calorimeter.
