Answer #1

The complete step wise calculation is given as below:-

@ 0.010 M HNO3 So, [ho = [No30 = 0.01m = 102m so, the concentration af [ho] will be [ro] = 102m] since, pH = -log [no] =-log

③ we have 0.035 m KOH So [oHo] = [ko] = 0.035m Then por = -log [ona = -log (0.035) om pom = E!)*(-1.456) = 1.456 since, PH +
