If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
The reaction reveals the dissociation of solid calcium hydroxide (Ca(OH)₂) into aqueous calcium ions (Ca²⁺) and hydroxide ions (OH⁻). The enthalpy change (ΔH) of -16.71 kJ indicates that the reaction is exothermic, meaning it releases heat to the surroundings. This suggests that when solid calcium hydroxide dissolves in water, it stabilizes into its ionic form, accompanied by a release of energy.
The reaction reveals that solid calcium hydroxide (Ca(OH)₂) dissolves in water to produce aqueous calcium ions (Ca²⁺) and hydroxide ions (OH⁻). The negative enthalpy change (ΔH = -16.71 kJ) indicates that the dissolution process is exothermic, meaning it releases heat to the surroundings. This suggests that the formation of ions from the solid is energetically favorable.
In this reaction, solid calcium hydroxide (Ca(OH)2) dissociates in water to form calcium ions (Ca2+) and hydroxide ions (OH-). This shows that calcium hydroxide is a strong electrolyte that completely dissociates into its constituent ions in water.

If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
The reaction shows that calcium hydroxide (Ca(OH)2) dissociates in water to form calcium ions (Ca2+) and hydroxide ions (OH-). This dissociation leads to the formation of two hydroxide ions for every one calcium ion.
In this reaction, Ca2+ reacts with NO2^1- to form Ca(NO2)2. The balanced chemical equation for this reaction is: Ca2+ + 2NO2^- → Ca(NO2)2.
The reaction ( \text{Ca(OH)}_2(s) \rightleftharpoons \text{Ca}^{2+}(aq) + 2 \text{OH}^-(aq) ) with a change in enthalpy (( \Delta H )) of -16.71 kJ indicates that the dissolution of solid calcium hydroxide in water is an exothermic process. This means that heat is released when calcium hydroxide dissolves, resulting in a slight increase in the temperature of the solution. The negative value of ( \Delta H ) suggests that the products (dissolved ions) are more stable than the reactant (solid calcium hydroxide) in terms of energy.
The reaction shows calcium ions (Ca2+) reacting with hydroxide ions (OH-) to form solid calcium hydroxide (Ca(OH)2) and release heat of 16.71 kJ. This reaction is exothermic, as indicated by the negative enthalpy change.
