What will a base produce when it dissolves in water?

a salt
water
hydroxide ions
hydrogen ions
the fourth one?

Now let's think about dumping a spoonful of NaOH, sodioum hydroxide, in a cup of water

looks like a lot of Na+ and OH- ions to me
OH- is NOT H+ !!!!!!

Try google for sodium hydroxide :)

When a base dissolves in water, it produces hydroxide ions (OH-) and the corresponding cation of the base. The cation could be a metal ion or another positively charged species. This combination of hydroxide ions and the cation is commonly referred to as a salt. So, the correct answer is A salt.
