The kinetics of corrosion of Aluminium in alkaline medium by weight - loss method was investigated. The corrosion kinetics was studied in potassium hydroxide at various time intervals at 20.0°C to 50.0°C. The result showed that the corrosion rate vary with different time interval and different potassium hydroxide concentration. Further, the effect of temperature, specific reaction rate, half-life time, energy of activation, entropy of activation and enthalpy of activation was evaluated.
