DETERMINATION OF CALCIUM AND PH ON PRODUCTS AQUA DI

PT. TIRTA SIBAYAKINDO

ABSTRACT

Determination of calcium and pH in aqua products in PT. Tirta Sibayakindo using
complexometric titration methods and tools conductivity meter is done for five
days. The results of the analysis obtained for calcium levels that first day = 23,00
mg / l, second day = 22,24 mg / l, third day = 22,36, fourth day = 22,36, and fifth
day = 22,36. And results obtained for levels of pH = 6,14first day, second day =
6,19, = 6,13, third day, fourth day = 6.16, and fifth day = 6,15. Value of calcium
and pH in aqua products in PT. Tirta Sibayakindo qualified drinking water quality
according to SNI.
