Sodium production - Corrosion Doctors

The cell does not produce calcium metal because the electrowinning of sodium occurs at a less negative hode potential than does the electrowinning of calcium. (In the absence of NaCl, electrolysis of CaCl 2 would indeed produce calcium metal at the hode, and calcium metal is produced in just this way.)

Calcium hydroxide | Ca(OH)2 - PubChem

Pure calcium hydroxide paste has a high pH (approximately 12.5-12.8) and is classified chemically as a strong base. Its main actions are achieved through the ionic dissociation of Ca (2+) and OH (-) ions and their effect on vital tissues, the induction of hard-tissue deposition and the antibacterial properties.
