The pH of the resulting solution is 9.96 that can be calculated by using the using the pOH values.
Buffer Solution is a water solvent primarily based totally answer which includes a combination containing a vulnerable acid and the conjugate base of the vulnerable acid, or a vulnerable base and the conjugate acid of the vulnerable base. They face up to a alternate in pH upon dilution or upon the addition of small quantities of acid/alkali to them.
Millimoles of NH3 = 0.316 x 250 = 79
Millimoles of NH4Br = 0.339 x 250 = 84.75
Millimoles of KOH = 57.3
pOH = pKb + log [salt - C / base + C]
= 4.74 + log [84.75 - 57.3 / 79 + 57.3]
= 4.04
pH + pOH=14
pH=14-4.04
pH = 9.96
