Hardness in water is mainly due to the presence of Calcium and Magnesium ions and each contributes to the amount of total hardness. Monitoring and controlling hardness is instrumental in order to prevent scaling and corrosion.

HI-3842 Hardness, High Range Test Kit information

Hanna's extended description

The HI-3842 hardness, high range test kit determines total hardness in water via a titrimetric method.

Water hardness has traditionally been defined as the capacity of water to precipitate soap. The ionic species in the water causing the precipitation was later found to be primarily calcium and magnesium. In the present, therefore, water hardness is actually a quantitative measure of these ions in the water sample. It is also now known that certain other ion species, such as iron, zinc and manganese, contribute to the overall water hardness. The measure and subsequent control of water hardness is essential to prevent scaling and clogging in water pipes.
