Is the reaction between HCl and NaOH endothermic or exothermic?

The reaction of HCl(aq), a strong acid, with NaOH(aq), a strong base, is an exothermic reaction. The big idea for most calorimetry themed demonstrations is energy is conserved.

What is the enthalpy of formation of NaOH AQ?

The standard enthalpy of formation of NaOH is -425.9 kJ/mol and the standard enthalpy of formation of NaOH (aq, 1 m) is -469.2 kJ/mol.

What kind of reaction is NaOH HCl?

neutralization reaction
Explanation: This reaction involve an acid (HCl) reacting with a base (NaOH), producing a salt (NaCl) and water. Therefore it’s a neutralization reaction.

What volume of HCl is needed to neutralize the NaOH solution?

So, you need 36.46 kg of HCl to neutralize 40.00 kg of NaOH .

What is the heat of reaction between HCl and NaOH?

The heat of reaction of one mole of H+ and OH- is 57.3 KJ. So, the heat of neutralisation of HCl and NaOH will be very cery close to 57.3 KJ per mole( As Both HCl and NaOH are strong elctrolytes so both of them quite easily without any considerable expense of energy furnish H+ and OH- ions respectively.

What happens when HCL and NaOH mix?

When HCl (Hydrochloric acid) and NaOH (Sodium Hydroxide are mixed they form Common salt (NaCl) and Water (H2O). This is an neturalization reaction as the acid and base react together to form a salt and water.

How do you calculate enthalpy of fusion?

Plug in values and evaluate to find the latent heat of fusion, LF, of the entire sample. The enthalpy of fusion ΔH fusion is related to LF by the equation ΔH fusion = LF n Where n is the number, in moles, of particles in the sample.

What is HCl plus NaOH?

HCl and NaOH are strong acid and strong base respectively and their titration curves are similar (shape of curve) in different concentrations. NaOH + HCl = NaCl + H 2 O . Both reactants and products are in aqueous state. Important factors and equations of HCl + NaOH reaction and its titration curve. HCl and NaOH reacts in 1:1 ratio (in same amount).
