WebPotassium 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. WebJan 13, 2024 · Because potassium hydroxide and sodium hydroxide are both strong bases, they react to water by releasing heat. So they are both highly exothermic. Their chemical similarity lends to a physical similarity as well. In solid form, they are both white powder or flakes. When dissolved they can each be used as an aqueous solution.
