MODEL RELEASED. Potassium chromate solution. Schoolboy holding up a round-bottomed flask containing potassium chromate solution. The chemical formula is K2CrO4. The yellow colour comes from the chromium ions rather than the potassium ions. Chromate ions are oxidising agents,able to strip electrons from some chemicals to alter their properties. This leads to uses ranging from tanning to photographic processing,printing,and pigments | |
