To Determine the Enthalpy of Neutralization of a Strong Acid(HCl) with a Sturdy Base (NaOH)
 1) Acetic acid is neutralized by NaOH with an enthalpy of -50.6 kJ mol1. Determine ΔH for the ionization of CH3COOH. Given that the heat of neutralization for a strong acid with a strong base is -55.9 kJ mol1? ΔHΔH = +5.3kJmol−1+5.3kJmol−1 ΔHΔH = −5.3kJmol−1−5.3kJmol−1 ΔHΔH = −10.6kJmol−1−10.6kJmol−1 None of these

 2) The heat of neutralization of a strong base and a strong acid is 57 Kj. The released when 0.5 mole of HNO₃ solution is added to 0.20 moles of NaOH solution, is 23.5 kJ -58.8 kJ -34.7 kJ 11.4 kJ

 3) Change in enthalpy of the system is the heat absorbed at a Constant temperature Constant volume None of these Constant pressure

 4) The change of enthalpy in an exothermic reaction is Negative Positive Any of these Constant

 5) The change of enthalpy in an endothermic reaction is Constant Negative Positive Any of these

 6) The value of the heat of neutralization depends on All of these The basicity of the acid The strength of the alkali The strength of the acid

 7) In a plastic cup with a lid, 50 cm3 of 1.0 mol dm-3 sulfuric acid and 50 cm3 of 2.0 mol dm-3 potassium hydroxide solution are added to each other at 28.5°C to estimate the heat of Neutralization. The mixture is then stirred, and a temperature of 41.5°C is the highest recorded. Calculate the Neutralization heat. [Specific heat capacity of solution: 4.2 J g-1 °C-1; density of solution: 1 g cm-3] 50.5kj of heat 32.6kj of heat 54kj of heat 54.6kj of heat

 8) The enthalpy of a substance (denoted by h), is defined as h = u-pv h = -u+pv h = u+pv h = -u-pv

 9) What happens when a solution of an acid is mixed with a solution of a base in a test tube? Temperature of the solution decreases None of these Temperature of the solution remain as same Temperature of the solution increase

 10) What should be done if a student's hand accidentally gets a few drops of strong acid on it? Wash the hand with saline solution After washing with plenty of water and apply solution of sodium hydroxide on the hand Neutralize the acid with a strong alkali Wash the hand immediately with plenty of water and apply a paste of NaHCO3
