Question
40 ml of 0.1 M ammonia solution is mixed with 20 ml of 0.1 M HCl. What is pH of themixture ?( pkb of ammonia solution is 4.74).
Options
A.4.74
B.2.26
C.9.26
D.5.00
Solution
NH3 + HCl → NH4Cl
pOH = pKb + log
pOH = 4.74 + log
pOH = 4.74 + 0 = 4.74
pOH = 14 - 4.74 = 9.26
pOH = pKb + log
pOH = 4.74 + log
pOH = 4.74 + 0 = 4.74
pOH = 14 - 4.74 = 9.26
