The Salifert Test for Alkalinity - Pictorial Guide

The start point. Just the indicator, with no KH reagent added:

Exactly 1 ml of reagent. The air in the body of the syringe doesn't matter; this is the air that was in the tip when you started drawing the liquid up and will stay in there, even if the syringe is emptied:

Just before the end point. On adding a drop and shaking, the liquid flashes pink before settling back to this grey colour:

This is the end point. The first hints of pink are showing, but it is still mainly grey. Make a note of the reading on the syringe and add another drop to make sure it turns properly pink:

This is one or two drops past the end point:

Reading the syringe - note the amount left - in this case 0.14 ml:

Find the appropriate line in the conversion chart. The alkalinity is given in meq/L, and can be converted to CaCO3 by multiplying this number by 50:
