With these components, the strips can detect a particular ion and create a distinct color change. It is important to note that PsH and NCH are mutually exclusive in the above formula: either the strong bases outweigh the strong … The ratio of the molar masses are: So total permanent water hardness expressed as equivalent of CaCO3 can be calculated with the following formula: The following calculator computes and gives an indication of the total water hardness. To handle this issue, you will have to treat the water. A measure of water hardness comes with many units. In its place, you can use the marked container in a water hardness testing kit.
