Complementary to its reactivity toward acids, KOH assaults oxides. Hence, SiO2 is attacked by KOH to give soluble potassium silicates. KOH reacts with carbon dioxide to offer potassium bicarbonate: Cyanide is unstable in water, though the reaction is slow right until about 170 °C. It undergoes hydrolysis to give ammonia and formate, which migh
