Answer #1

HI ------------------------------------- NaOH

MA = 0.13M ----------------------- MB = 0.11M

VA   = 108ml ------------------------VB = 111ml

M   =    MAVA-MBVB/VA + VB                 [ MAVA >MBVB]

      = 0.13*108-0.11*111/(108+111)

     = 1.83/219

      = 0.008356

[H^+]   = M = 0.008356M

PH   = -log[H^+]

        = -log0.008356

       = 2
