9. DATA PENGAMATAN

9.1 standardisasi larutan std sekunder NaOH dengan KHP

Rata-rata volume titran (NaOH)=(4,3ml+3,9ml+3,5ml)/3=(11,7ml)/3=3,9ml

9.2 Standardisasi larutan std sekunder HCl dengan Na2CO3

Rata-rata volume titran(HCL)=(2,3ml + 2,1ml + 2ml)/3=(6,4ml)/3=2,1333ml

Mg rata-rata Na2CO3

=216,8 mg

9.3 Penentuan konsentrasi std CH3COOH dengan larutan std NaOH

Rata-rata volume titran(NaOH)=(3,5ml+3,2ml+3,3ml)/3=(10ml)/3=3,3333ml

9.4 Penentuan konsentrasi larutan NH 4OHdenganlarutan HCl

Rata-rata volume HCL=(1,2ml + 1,4ml + 1,9ml)/3=(4,5ml)/3=1,5ml
