| VISOCOLOR® ECO Chloride |
| Colorimetric determination of chloride |
 |
Chloride ions react with mercuric thiocyanate to produce undissociated mercuric chloride
and to liberate thiocyanate ions. In the presence of ferric salts these thiocyanate ions produce a
characteristic orange colour. |

reach high values. |
