How do I substitute ManVer® 2hardness indicator powder with ManVer® hardness indicator solution?
Substituting ManVer® 2 hardness indicator powder for ManVer® hardness indicator solution
Four drops of Hardness 2 Indicator Solution or a 0.1-g scoop of ManVer®2 Hardness Indicator Powder can be added in place of the ManVer®2 Hardness Indicator Powder Pillow. The volume of 4 drops is approximately 0.20-0.28 mL (approximately 0.05-0.07mL/drop). The indicator concentration shouldn’t contribute significantly, but it is best to use the least amount that provides a good, visible color change at the endpoint.
