2OH⁻ (aq) represents two hydroxide ions in an aqueous solution. Hydroxide ions are negatively charged and consist of one oxygen atom bonded to one hydrogen atom (OH⁻). In water, these ions can contribute to the solution's alkalinity, making it basic. The presence of hydroxide ions is common in strong bases, such as sodium hydroxide (NaOH).
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
This reaction is exothermic.
This reaction is exothermic.
The reaction is endothermic.
This is a precipitation chemical reaction.
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
Write the ionic and net ionic equations and it turns out there is no reaction.Ca^2+(aq) + 2OH^-(aq) + 2NH4^+(aq) + SO4^2-(aq) ==> Ca^2+(aq) + SO4^2-(aq) + 2NH4^+(aq) + 2OH^-(aq) ... ionic equation.NOTE: all species are soluble, therefore NO REACTION
the reaction produces heat
This reaction is exothermic.
Ca2+ + 2OH- + 2H+ + SO42- -------> 2H2O + Ca2+ + So42- 2OH- + 2H+ -------> 2H2O
Mg2+ (aq) + 2OH- (aq) → Mg(OH)2 (s) → Blue complex
Mg2+ (aq) + 2OH- (aq) → Mg(OH)2 (s) → Blue complex
This reaction is exothermic.
The reaction is endothermic.
BeCl2(aq) + 2NaOH(aq) -> 2NaCl(aq) + Be(OH)2(s) Be(aq) + 2OH(aq) -> Be(OH)2(s) Hope this helps!
The reaction produces heat.
