Complementary to its reactivity towards acids, KOH assaults oxides. Hence, SiO2 is attacked by KOH to present soluble potassium silicates. KOH reacts with carbon dioxide to offer potassium bicarbonate:This is often made up of a stable base (KOH) as well as a weak acid (HCN). This is used for that extraction of gold, silver, as well as other metal
