Chemex (surface water) alkalinity – d.l. = 2

Chemex, surface water; alkalinity – detection limit is 2 ppm

General Methodology:

Alkalinity in waters was determined by titrating a 25 ml aliquot of the sample with 0.02 N H2SO4 using a Corning combination electrode and a Corning model 135 pH meter.  The end point was pH 4.5.
