JazakAllah khairan........thank you so much for your help!! Alhamdulilah i got it now..! May Allah grant you and your family with Jannah tul firdous..!!Ka is for the acid. The acid contains H2PO4- ion hence, NaH2PO4 is the acid.
PH = pKa + log [salt]/[acid]
PH = -log(6.3*10^-8) + log [.1]/[.2]
PH = 6.89
