Below are two thermochemical equations for the neutralization process.
KOH + HNO₃ → KNO₃ + H₂O ∆H = -57kJ/mol
KOH + CH₃COOH → CH₃COOK + H₂O ∆H = -55kJ/mol
The value of the heat of neutralization for both processes are different because
In a neutralization reaction, 50 cm³ of 1.0 mole dm⁻³ nitric acid reacted with
50 cm³ of 1.0 mole dm⁻³ sodium hydroxide solution. Which of the following
acids can replace 50 cm³ of 1.0 mole dm⁻³ nitric acid to release the same quantity
of heat?
Which of the following acid releases the highest amount of heat when reacted with excess sodium hydroxide?
When 100 cm³ of 1.0 mol dm⁻³ of sodium hydroxide is added to 100 cm³ of 1.0 mol dm⁻³ of hydrochloric acid, the temperature rises by 7°C. Which of the following mixtures will produce an increment of 14°C in temperature?
When 50 cm³ of 1.0 mol dm⁻³ nitric acid is mixed with 50 cm³ of 1.0 mol dm⁻³ sodium hydroxide solution the temperature increases by 6.0 °C . What is the temperature change if the experiment is repeated using 50 cm³ of 2.0 mol dm⁻³ nitric acid with 50 cm³ of 2.0 mol dm⁻³ sodium hydroxide?
Which of the following hair of acid and alkali produces the highest heat of neutralisation?
