    DESCRIPTION

    General description

    Potassium hydroxide, also known as caustic potash, is a water soluble strong base. The electron scattering in KOH has been investigated.[1] Its infrared spectrum has been recorded and analyzed.[2] The impact of surface functionalization of active carbons using KOH has been studied.[3] Its role as a catalyst in the Michael addition reaction has been explored.[4]

    Application

    Potassium hydroxide (KOH) has been used to prepare methanolic-KOH that is employed in a protocol for saponification of fruit extracts.[5]
    KOH has been used for adjusting pH during the preparation of the following:[6]
    • Murashige and Skoog (MS) agar plates
    • MS liquid medium
    • MES ((2-(N-morpholino)-ethanesulfonic acid hydrate) solution
    • microtubule stabilizing buffer (MTSB)
    • 4% paraformaldehyde fixative (PFA)
