acid
This substance is a base.
A base
When KOH is placed in water, it ionizes to K+ and OH-, so the polyatomic ion is the OH- (hydroxyl anion).
Hydrogen gas, H2.
Ammonium (cation): NH4+ Hydroxyl (anion): OH- It is incorrect to write NH4OH solution, because the solution is of ammonia (NH3) in water.
This substance is a base.
If a substance produces hydroxyl ions (OH-) when dissolved in water, it is referred to as a BASE.
This substance is a base.
A substance that releases hydroxyl ions in water is a base. Bases are substances which in water, becomes slippery, has a bitter taste, changes indicator color, forms salts with acids and promotes base catalysis. Alkaline earth materials is an example of a base.
A base
This substance is an acid.
An acid plus a base will yield a salt and water. In textbooks this is often written as: HA + BOH yields AB + HOH The above means an acid with its hydronium ion added to a base with its hydroxyl group will yield a salt composed of the acid and the base plus water (hydrogen plus hydroxyl is HOH or H2O).
When KOH is placed in water, it ionizes to K+ and OH-, so the polyatomic ion is the OH- (hydroxyl anion).

There is no such chemical symbol. 'OH' does not exist as a substance. However, the symbol 'OH^-' does exist, it is the symbol for the hydroxide anion(ion). Further when 'OH^-' is shown in a substance , e.g. NaOH , the 'OH^- ,moiety still exists but is cancelled out by the 'Na^+' Two equal and opposite charges.
Hydrogen gas, H2.
