A base does this. The hydroxide (OH-) ion appears in solution. An acid produces hydrogen (or hydronium) ions in solution, and not hydroxide ions.
A base in solution will produce hydroxide or OH- ions.
A base is a compound that produces hydroxide ions (OH-) in solution.
A base.
False
It is a base as it is a solution of calcium hydroxide.
It Produces a hydroxide ion
yes
Ahh, Svante Arrhenius. Cool guy. Wish I'd met him. Anyway, Arrhenius created a definition for an acid and for a base -- Acid - a substance which produces hydronium ions (H3O+) in aqueous solution Base - a substance which produces hydroxide ions (OH-) in aqueous solution That's it!
A base in solution produces hydroxide ions (OH-) as the predominant ion.
The neutralization of citric acid and sodium hydroxide is an acid-base reaction. Citric acid, being an acid, reacts with sodium hydroxide, a base, to form water and a salt (sodium citrate), resulting in a neutral pH solution.
This substance is an acid.
