Why is Sodium hydroxide a base when reacted with sulphuric acid?
Isn't sodium hydroxide (NaOH) always a base because it has OH in it?
Surely its because the OH- ion is accepting a proton.
but are there any substances with OH in them which aren't bases, i didnt mean it HAS to have OH to be a base, just that most (if not all substances) with OH are bases.
sodium hydroxide can gives OH- ion so it acts as a base while sulphuric acid can provide H+ ion, it acts as an acid, these two ions combine together and form water, so that is the basic acid-base neutralization to give off water.
sulphuric acid has OH in it and it certainly isn't a base, so does phosphoric acid and nitric acid in fact all the oxy-acids have the O-H group
and as for alcohols...
