HI3815 HANNA ชุดทดสอบคลอไรด์ Chloride Test Kit

Description

The HI3815 chloride test kit is quick, easy to use and portable. Chloride is one of the most common ions present in water.
During testing, when colour change is achieved, under careful conditions - usually using a burette – the reagent is added, drop by drop, until the solution turns to the colour required. The user will then count how many drops of reagent were used to achieve complete colour change. The number of drops used will determine the chemical concentration and results can be found in the manual included.
The design makes the kit easy to handle and, except for mercuric solution, practically prevents accidental injury or damage due to spills. The pH is lowered to approximately 3 by addition of nitric acid. Mercuric ions react with chloride ions to form mercuric chloride. The colour change from yellow to purple determines the end point of this titration.
