Increasing calcium ion concentration: the concentration of calcium ions in solution can be increased by improving the solubility of Ca(OH)2 in water using organic additives like phenol and sugar. 3. Buffering: This is done to maintain the pH of the solution at the optimum of 9.5 - 10 which favours hypochlorite formation using Ca(OH)2.

Calcium in biology - Wikipedia

Calcium ions (Ca 2+) contribute to the physiology and biochemistry of organisms' cells.They play an important role in signal transduction pathways, where they act as a second messenger, in neurotransmitter release from neurons, in contraction of all muscle cell types, and in fertilization.Many enzymes require calcium ions as a cofactor, including several of the coagulation factors.

Calcium in Plants

Calcium is an essential plant nutrient. It is required for various structural roles in the cell wall and membranes, it is a counter‐cation for inorganic and organic anions in the vacuole, and the cytosolic Ca 2+ concentration ([Ca 2+] cyt) is an obligate intracellular messenger coordinating responses to numerous developmental cues and environmental challenges.

Calcium - Plant Propagation - European Medical

Although calcium can be present in millimolar concentrations within the plant as a whole, calcium ions are pumped out of the cytoplasm of cells. Ca2+ is sequestered in the vacuole, complexes with calcium-binding proteins and may precipitate into calcium oxalate crystals to maintain the concentration at around only 0.1 mM.
