is KOH an acid or base?

Answer 1

base, anything with hydroxide, OH, is a base
anything with hydronium atoms, H, is an acid

Answer 2

It's a base.

Potassium hydroxide is an ionic compound, with a positive potassium ion, and a negative hydroxide ion. (The hydroxide ion is made of an oxygen atom covalently bonded to a hydrogen atom. It reacts as a unit.)

When put into water, the polar water molecules will split up the compound into its ions.

KOH + H2O --> K+ + OH-

And the hydroxide is what gives a base the properties of a base.

Answer 3

the chemical compound potassium hydroxide, (KOH) sometimes known as caustic potash, potassa, potash lye, and potassium hydrate, is a metallic base. It is very alkaline.

agriculture, potassium hydroxide is used to correct the pH of acidic soils. It can also be used as a fungicide or even a herbicide. MEMS.

[edit] Food preparation

Food uses of lye include washing or chemical peeling of fruits and vegetables, chocolate and cocoa processing, caramel color production, poultry scalding, soft drink processing, and thickening ice cream. Olives are often soaked in lye to soften them, while pretzels and German lye rolls are glazed with a lye solution before baking to make them crisp.

Lye is used to make the Scandinavian delicacy known as lutefisk (from lutfisk, "lye fish"). Cod is soaked in lye to a jelly-like consistency, then served with bacon fat, potatoes, brunost sauce and mushy peas. Hominy is dried maize (corn) kernels reconstituted by soaking in lye.

Answer 4

It is a metallic base. It contains hydroxide (OH-) which is a base. If something contains Hydrogen (H+) then it is an acid.

Answer 5

its strong base
