What is the pH at the equivalence point an HF/NaOH titration?

At this point, there are no moles of HF left and (0.020 L)(1.5 mol/L) = 0.030 mol of F-. Compute the molarity of the fluoride now. The volume of NaOH that was required to reach the equivalence point was (0.030 mol)/(1.0 mol NaOH/L) = 30 mL. The total volume of the solution at the equivalence point is 30 mL + 20 mL = 50 mL.

In this case there are moles of a strong acid (HCl) and its salt (NaCl). But the salt of a strong acid and a strong base does not effect the pH of water, so we left with only moles of HCl in the mixture. To calculate the pH of the solution we must determine the concentration of HCl in the mixture. The concentration is obtained by dividing the ...

Conductivity of aqueous HCl NaOH and NaCl solutions: Is ...

Jan 29, 2015 The conductivity of the HCl solution is higher compared to the NaOH solution due to higher mobility of the H 3 O + ions. The transition to the NaCl solution, in some sense, is a test for reasonability of the above. In our model the dc-active H 3 O * and OH * ions are produced by the HCl and NaOH molecules.

What is the enthalpy of neutralization of HCl and NaOH?

Jun 15, 2020 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.
