Infobox references

Potassium ethoxide, also known as potassium ethanolate, is an off-white or yellow powder with the chemical formula of C2H5KO. Potassium ethoxide contains an ethoxide ion, the conjugate base of ethanol, which makes these compounds strongly basic. It hydrolyzes to yield ethanol and potassium hydroxide.
