Nope, hydroxide ion.
The hydroxyl anion ( OH- ) is found in many (but not all) bases.
Ni2+
The correct formula for phosphate ion is PO4^3. Phosphate carries a negative charge and is the conjugate base of hydrogen.
The conjugate base of perchloric acid is the ion chlorate (ClO4)-.
Generally, a base will accept an H+ ion rather than donate one. In some cases a substance that normally acts as a base can donate an H+ ion, but in that situation, it is said to be acting as an acid. A substance that can act as both an acid and a base is said to be amphoteric. As and example, the bicarbonat ion, HCO3+ is generally considered a base, as it accepts a hydrogen ion to form carbonic acid, H2CO3, however, n some cases it can donate its remaining H+ ion to a stronger base to form a carbonate ion CO32+. This can be seen in the reaction between sodium bicarbonate and sodium hydroxide. NaHCO3 + NaOH --> Na2CO3 + H2O The bicarbonate ion, acts as an acid, donating a hydrogen ion to the hydroxide ion, forming a carbonate ion and a water molecule.
The conjugate base of HF is the fluoride ion F-
Ni2+
The correct formula for phosphate ion is PO4^3. Phosphate carries a negative charge and is the conjugate base of hydrogen.
The hydroniumion is absorbed by a base in water. It reacts in a neutralization reaction with something acidic, generally referred to as an H+ ion.
Cu the ion of copper is generally Cu 2+

The Chemical Formula for Potassium Ion is K+.
Acetate ion is CH3C00-, C2H3O2-. It is the conjugate base of acetic acid, CH3COOH
The polyatomic ion is a carbonate ion, with formula CO3-2.
The polyatomic ion is a carbonate ion, with formula CO3-2.
The chemical formula of hydronium ion is (H3O)+.For the "oxide ion" check your spelling.
