Potassium Chromate Pure indicator for determination of Chloride by titration method.

Prompt industrial dispatch Bulk & custom packaging (20L, 25L, 210L, IBC) Certificate of Analysis (COA) & MSDS available

Product Overview

Potassium Chromate is used as an indicator in the determination of Chloride by titration with standard Silver Nitrate solution. This method is called the Mohr method of determining Chloride and is based on the formation of a red precipitate of Silver Chromate at the endpoint after all the Chloride has been precipitated as white Silver Chloride. A 5% solution of Potassium Chromate that has been Chloride neutralized is commonly used. Approximately 1 mL of this indicator should be used per 100 mL of sample volume.

Application & Dosage

Application Instructions


Available Packaging & Quantities

For comparison purposes, all Mohr tirations should be carried out at about the same temperature, since the solubilities of Silver Chloride and Silver Chromate depend on temperature. Good stirring during the addition of the Silver Nitrate is also required; otherwise, Silver Chromate that forms locally before the endpoint can become occluded in the Silver Chloride precipitate instead of redissolving. Poor agitation could lead to an endpoint that is neither sharp nor reproducible. The reactions for the Mohr titration are:

 
Ag+ + Cl- → AgCl (white precipitate)
 
2 Ag+ (excess) + CrO42- → Ag2CrO4 (red precipitate at endpoint)
