The ph value of potassium oxide
WebbPotassium tert-butoxide (or potassium t-butoxide) is a chemical compound with the formula [(CH 3) 3 COK] n (abbr. KOtBu). This colourless solid is a strong base (pKa of conjugate acid around 17), which is useful in organic synthesis.The compound is often depicted as a salt, and it often behaves as such, but its ionization depends on the solvent.
