Question

Hitunglah ph larutan yang terbentuk dari campuran berikut 150 ml larutan ch3cooh 0,1 m+100 ml larutan naoh 0,1 m. ka ch3cooh=1x 10^-5

Answer 1

n ch3cooh = 150 x 0,1 = 15

n naoh = 100 x 0,1 = 10

M= 15 10 - - (PENYANGGA

B= -10 -10 10 ASAM)

S=5 0 10

pH = Ka x asam lemah/anion asam

= 10^-5 x 5/10

= 0,5 x 10^-5

= 5 x 10^-6

= - log 5.10^-6

= 6 - log 5

Insya allah benar
