Yes
An alkali.
NO because it cannot
I'm assuming you mean a salt neutralising an acid or base- This can not actually happen, because a salt is already 'Neutralised' An acid can neutralise a base, and a base neutralise an acid, but when Base+Acid reacts, a salt is formed. Adding a salt to a acid or base solution will only make it salty.
