Complementary to its reactivity toward acids, KOH assaults oxides. As a result, SiO2 is attacked by KOH to give soluble potassium silicates. KOH reacts with carbon dioxide to offer potassium bicarbonate:A single route includes melting cyanuric acid or urea with potassium hydroxide. This provides potassium cyanate. Crush the ensuing sound and grind
