By binding to these heavy metals and carrying them out of the body through the urine, EDTA reduces the body’s toxic metal burden and helps slow the process of atherosclerosis. EDTA also removes excess calcium from artery walls, making them more responsive and better able to dilate.

Human digestive system - Calcium | Britannica

Human digestive system - Human digestive system - Calcium: Calcium is required for the construction of bone; it forms part of the substance cementing together the walls of adjacent cells; and it is vital in the responsiveness to stimuli of muscle and nerve cells, which determines their excitability. The main sources of calcium are milk and milk products; meat, in which it is bound to proteins

Calcium nitrate - Wikipedia

Determination of Calcium Ion Concentration

calcium ions changing colour from blue to pink/red in the process, but the dye–metal ion complex is less stable than the EDTA–metal ion complex. As a result, when the calcium ion–PR complex is titrated with EDTA the Ca2+ ions react to form a stronger complex with the EDTA. For the titration, the indior is added to the sample

Remove calcium from pool surfaces without draining the water.

Calcium can also form a thin calcium film that covers dirt or metal stains on the pool interior. Although calcium carbonate is white, in this case, it may look brown or grey because the dirt has discoloured and contaminated the calcium. When this happens, the calcium staining will look brown or discoloured.
