Step-by-step explanation
Step 1.
Half Equivalence point is the point at which half of the acid has been neutralized
The initial moles of 
At one-half the equivalence point, the amount of added base is exactly one-half the initial amount of acid.The base converts exactly half of the 
into 
resulting in equal amounts of the weak acid and its conjugate base. The pH is therefore equal to pKa.
Since here 
Hence,
