What is the mixture of barium hydroxide and sulfuric acid?

In dilute solution [math]Ba(OH)_2 + H_2SO_4 = BaSO_4 + 2H_2O[/math] Barium sulphate is insoluble and precipitates. If the sulphuric acid is very strong the barium sulphate does not precipitate. read more

Barium sulfate is extremely insoluble in water and virtually all of it will precipitate and quickly sink to the bottom of its container since it’s also very dense. Because of its insolubility, the reaction will go to completion. No barium hydroxide will be left in solution if the sulfuric acid concentration equals that of the barium hydroxide. read more
