If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
No. elemental calcium is Ca. The calcium ion is Ca2+
Ca2+

If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
A white precipitate, that appears to be milky. Ca^2+(aq) + 2OH^-(aq) = Ca(OH)2 (s)
This is the net ionic equation for the formation of calcium hydroxide, Ca(OH)2 precipitate from soluble calcium ions and soluble hydroxide ions.
Ca(OH)2 + 2HCl ---------> CaCl2 + 2H2OIonic Ca2+ + 2OH- + 2H+ +2Cl- -----------> Ca2+ +2Cl- + H2ONet Ionic: H+ + OH- -----------> H2O
