  3. Determining the pH of solution drinks using pH meter. • Comparing the results of pH measurements using a universal indikator with a pH meter. AIM

  4. APPRATUS / CHEMICALS • APPRATUS CHEMICALS • pH meter Aquadest • 12 beaker 200 ml size Soda • 2 beaker 400 ml size Soap sirih liquid • pH meter Pocari sweat • Test tube Kiranti Vit.A.IPI • Vit. Lemon • Cofee and Tea

  5. PROCEDURES 1. Reconstituted various beverages and chemicals frequently used in 50 ml beaker. 2. pH estimated using the universal indikator of acid – base. 3. pH is determined using a pH meter. Note : Before measuring the pH electroda was immersed in the buffer or aquades.

  6. THE RESULT OF EXPERIMENT USING THE UNIVERSAL INDICATOR TEA : pH = 7 VIT. LEMON : pH = 4 POCARI SWEAT : pH = 4 COFEE : pH = 5 KIRANTI : pH = 4 SOAP SIRIH LIQUID : pH = 9 SODA : pH = 9 VIT. A . IPI : pH = 8 • USING A pH METER • TEA : pH = 5 • VIT. LEMON : pH = 3,04 • POCARI SWEAT : pH = 4,9 • COFEE : pH = 5 • SOAP SIRIH LIQUID: pH = 13,79 • SODA : pH = 8,58

  7. BY USING pH - METER ,WE CAN FIND THE INFORMATION OF pH DIRECTLY BY A DIGITAL SCREEN ON THE INSTRUMENT. • BUT, BASICALLY, MEASURING pH USING THE UNIVERSAL INDICATOR CAN GIVE A MEASUREMENT RESULT WHICH IS MORE PRECISE. CONCLUSION

  8. PROCESS SKILL • READING SCALE • MEASURING pH • INTERPRATE OF THE DATA
