citric acid ppm drop
Hi. Today i did an experiment with my tap water.
My tap is 120 ppm EC. german hardness 6-7.Ph 8
First i added phosphoric acid to ph of 6. total ec stayed +/- same
then i added citric acid to ph of 6 . total ppm dropped from 120 to 90.
What is happening in my water solution with citric acid. Why does my EC-meter show a drop in EC with citric acid , why doesnt it with phosphoric ?
Has it maybe something to do with chelation ?
