Drain cleaner is sodium hydroxide in solution, which is a powerful base.
it is usually sodium hydroxide - a base
I believe it is an alkali ( base ) and that alkali is sodium hydroxide, NaOH.
It depends on the type of drain cleaner. Some are acidic (i.e. sulphuric acid based) and some are basic (i.e. sodium hydroxide based), but it would be unlikely that a drain cleaner would have a neutral pH.
sulphuric acid
Calcium Hydroxide + Hydrochloric acid = Calcium chloride + Water

calcium hydroxide and gastric acid can they be reversed?

sulphuric acid
Calcium Hydroxide + Hydrochloric acid = Calcium chloride + Water
An acid reacting with a hydroxide will result in the formation of water and the corresponding salt of the hydroxide's cation and the acid's anion. So in this case the products are water and calcium nitrate.
Hydrochloric acid Sulfuric acid Phosphoric acid Sodium hydroxide Calcium hydroxide Potassium hydroxide
calcium chloride +water
Calcium Carbonate
No, because one mole of calcium hydroxide constitutes two equivalents of calcium hydroxide for neutralization, but one mole of phosphoric acid constitutes three equivalents of phosphoric acid for neutralization. Therefore, one mole of calcium hydroxide will neutralize only 2/3 of one mole of phosphoric acid.
The reactions of sodium hydroxide and calcium hydroxide with sulfuric acid will produce sodium sulfate and calcium sulfate respectively (water will be another product in both reactions. Sodium sulfate is soluble in water and so will remain in solution. Calcium sulfate, however, is insoluble and will precipitate as a solid.
