Because they do
Calcium hydroxide, Ca(OH)2 is a base and neutralizes acid. When a solution is acidic it contains excess hydrogen (H+) ions, calcium produces the hydroxide ion (OH-) in water, which reacts wit h the H+ ions to produce water. OH- + H+ --> H2O
I have done my best to research this answer and my best assumption is that the substance does not exist. What does exist is Ca(C2H3O2)2 and this would be the formula for calcium acetate. It can not be calcium carbide mixed with calcium hydroxide or other such moiety. Further contributions in the discussion area please.
sulphuric acid + lithium hydroxide ---> lithium sulphate + water
Potassium hydroxide is a strong alkali. Therefore it can be neutralized by using a strong acid such as nitric acid or sulfuric acid.
By using calcium deposits
Carbon Dioxide will change limewater (calcium hydroxide) into calcium carbonate. This shows as a white precipitation (milky).

Laboratory preparation of ammonia or NH3 requires using ammonium chloride and calcium hydroxide. The reaction equation is 2NH4Cl plus CaOH2 gives the products 2NH3 plus CaCl2 plus 2H2O. The ammonium chloride and calcium hydroxide are heated for this reaction.
It dissolves the hair using calcium hydroxide and sodium hydroxide (lye); this allows the hair to be easily scraped off.
They protective by using their spiky quills
Using Downs process, by the electrolysis of molten sodium chloride. This is done in a Downs Cell in which the NaCl is mixed with calcium chloride to lower the melting point below 700 °C. As calcium is less electropositive than sodium, no calcium will be deposited at the cathode. This method is less expensive than the previous Castner process of electrolyzing sodium hydroxide.
Salt is made up of calcium and chloride. Calcium is a necessary ingredient to a good diet.

Carbon Dioxide turns lime water milky/cloudy.
Sodium hydroxide will cause damage to the skin, but is extremely damaging to the eyes.
