PENGARUH KEASAMAN DALAM CAIRAN PEMBERSIH ORGANIK UNTUK MELARUTKAN KERAK YANG DISEBABKAN CALSIUM PADA AIR SADAH

Abstract

Organic waste is a waste that can be perfectly described by biological processes either aerobic or anaerobic. Organic waste can also be processed into a cleaning fluid that is used to dissolve the crust through the fermentation process. The raw materials used in the manufacture of organic cleaning fluids are food and beverages left over.
The study was conducted in May - June 2015 at the Laboratory of Chemical Analyst of Health Analyst Delima Husada, Jl. Arief Rahman Hakim No. 2B Gresik with quantitative analysis of complexometric method to see the solubility of calcium and alkalimetry method to see the acid content in organic cleaning fluid.
Based on the results of CaCO3 solubility analysis at 60 ml volumes organic cleansing liquid containing acid can dissolve calcium with concentration > 500.1 ppm.
