1} A base if vdissolved in water will show the presence of OH- ion
2}a base if it is an oxide of a metal will show the presence of an O-- ion in fused state
3} if we are studying bases like the soda amide which is used in organic reactions then the ion it will form when dissolved in water will be again OH- ion
NaNH2 +H2O------->NaOH+NH3, NaOH------>Na+ + OH-
4} NH3 is also a base but it has an e- pair on N which it donates to H+ when dissolved
in water and forms NH4+ ion
the H+ ion will be present in weakly dissociated water as water generally contains some salts in the natural state and that accounts for the slight dissociation of water

How can bicarbonate be a weak base if it doesn't contain hydroxide ion?
The bicarbonate ion is a base because it's a proton acceptor, that being one of the definitions of a base.
Can ammonia NH3 be classified as a base even though it does not contain the hydroxide ion OH Why or Why not?
NH3 can accept a proton ( hydrogen ion ) to become NH4(-), ammonium. This is the definition of a base; accepting protons. NH3 is a weak base.
What type of ionic compound does the positive ion of a base and the negative ion of an acid combine to form?
salt
Compounds with both ionic and covalent bonds contain this type if ion?
Compounds with both ionic and covalent bonds contain polyatomic ions.
What type of magnetic charge do ferric and ferrous ions contain?
If you mean electric charge the ferric ion has a 3+ charge, the ferrous ion has a 2+ charge.
How is acid and base a different meaning?
An acid contain the ion H+ or (COOH)+ and a base contain the ion (OH)-.
Which ion is absorbed by a base in water?
The ion that is absorbed by a base in water is the hydronium ion. It is considered a type of acidic ion.
What ion produce in base solution?
All acids contain a hydrogen ion, H+. All bases contain a hydroxide ion, OH-
How can bicarbonate be a weak base if it doesn't contain hydroxide ion?
The bicarbonate ion is a base because it's a proton acceptor, that being one of the definitions of a base.
What type of acid or base is the ammonium ion?
acid ( {NH4}+ )
Can ammonia NH3 be classified as a base even though it does not contain the hydroxide ion OH Why or Why not?
NH3 can accept a proton ( hydrogen ion ) to become NH4(-), ammonium. This is the definition of a base; accepting protons. NH3 is a weak base.
What type of ionic compound does the positive ion of a base and the negative ion of an acid combine to form?
salt
What are acid base and salts?
Acids contain the ion H+ or (-COOH)-. Bases contain the ion OH-. Salts are the products of an acid/base reaction; they contain the cation from the base and the anion from the acid.
Which ions or chemicals make a substance base?
Arrhenius bases will always contain a hydroxide ion (OH-).
What is the base in a reaction?
The base in a chemical reaction is the species that either (a) accepts a proton, (b) produces an OH- ion, or (c) is an electron donor.
What is the difference nitride sulphite and phosphate in chemistry?
A nitride contain the ion N3-, a sulphite contain the ion SO3-, a phosphate contain the ion (PO4)3-.
Compounds with both ionic and covalent bonds contain this type if ion?
Compounds with both ionic and covalent bonds contain polyatomic ions.
