Answer:
Explanation:
282000 j/mol *1 mol/6*10^(23) = 4.7*10^(-19) J for one electron
The pH of the solution is determined by the hydrogen ion concentration. The pH of the solution with 1.5 M NH4Cl and 0.50 M NaOH is 8.77.
<h3>What is pH?
</h3>
The potential of the hydrogen ion in the given solution is called pH which determines the acidity and basicity of the solution.
Given
The molar concentration of 500 mL NH4Cl = 1.5 M
The molar concentration of 500 mL NaOH= 0.50 M
Kb (NH3) = 1.8 × 10 -5
First pOH is calculated as,
pOH = pKB + log [NH4Cl][NaOH]
= - log 1.8 × 10-5 + log [1.5][0.50]
= - log 1.8 × 10-5 + log [3]
= 4.744 + 0.477
= 5.221
Now, pH is calculated from pOH as,
pH + pOH = 14
pH = 14 – pOH
= 14 – 5.221
= 8.77
Thus we found that, 8.77 is the pH of the solution with 1.5 M NH4Cl and 0.50 M NaOH.
