Pka toluene
Webp-Toluenesulfonic acid. Molecular Formula CHOS. Average mass 172.202 Da. Monoisotopic mass 172.019409 Da. ChemSpider ID 5876. 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.
