Can we perform the charcoal cavity test without the addition of fusion mixture (Na_(2)CO_(3) and K_(2)CO_(3)) with the carbonate of metals? |
| Answer» SOLUTION :Yes, we can directly perform the charcoal cavity test WITHOUT the addition of fusion mixture because the latter simply converts the substances into CARBONATES in fused state. Carbonates of METALS on heating in the charcoal cavity are reduced to metallic state. | |
