Question

Hitung jumlah PH 100ml CH3COONa 0.01M ka 10-6

Answer 1

H+ =√10-14/10-6 x 0.01
     =√10-10
     =10-5

ph=-log 10-5
    =5

Answer 2

V = 100 ml CH3COONa
0.01 M
ka = 10 ^-6

G = 0.01/100 = 0.0001 = 1 x 10^-4

[OH-] = akar kw/ka . G
           akar 10^-14/ 10^-6 . 10^-4
           akar 10^-12
           10^-6
poh = 6
ph=pkw -poh
    = 14 - 6
    = 8
