Formula
Variables
- m — Total solution mass (g)
- dT — Temperature rise (K)
- n — Water moles formed (mol)
- c — Specific heat of solution (J/(g·K))
Worked example
With total solution mass = 100 g, temperature rise = 6.8 K, water moles formed = 0.05 mol, specific heat of solution = 4.184 J/(g·K), the calculator gives enthalpy of neutralization ≈ -56.9024 kJ/mol; heat released ≈ 2.84512 kJ.
Frequently asked questions
What is the enthalpy of neutralization calculator used for?
Find the enthalpy of neutralisation from the temperature rise of an acid base mixture in a calorimeter. It helps with questions such as “enthalpy of neutralization”, “heat of neutralisation”, “acid base calorimetry”.
What is the formula for the enthalpy of neutralization calculation?
Enthalpy of neutralization (kJ/mol) = -m × c × dT / n / 1000. Heat released (kJ) = m × c × dT / 1000. Here m is total solution mass (g), dT is temperature rise (K), n is water moles formed (mol), c is specific heat of solution (J/(g·K)).
What inputs do I need for the enthalpy of neutralization calculator?
You need total solution mass in g, temperature rise in K, water moles formed in mol, specific heat of solution in J/(g·K). Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the enthalpy of neutralization calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the enthalpy of neutralization result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
