CHLORIDE TEST KIT
Chloride is a major constituent of sea water and is extremely corrosive in acidic environments. Chlorides may also get into surface water from several sources including:
1) rocks containing chlorides;
2) agricultural runoff;
3) wastewater from industries;
4) oil well wastes;
5) effluent wastewater from wastewater treatment plants, and;
6) road salting.
Therefore, water that is used in industry or processed for any use has a recommended maximum chloride level. It requires close monitoring in applications such as boiler systems, close loop cooling water systems, cooling towers etc.
APPARATUS
...................1 Test Tube ................................Code ..............................0778
...................1 Titrator...................................... Code.............................. 0378
REAGENTS
...................Chloride Reagent.1....................... Code............................. 4504 - E
...................Chloride Reagent.2....................... Code............................. 4505 - H
...................Phenolphthalein Reagent............ Code............................. 2246 - E
..................Sulphuric Acid Reagent (0.5 N.)... Code............................. 6090 - E
PROCEDURE
1. Fill the Test Tube (0778) to 15 ml level with water sample.
2. Add one drop of Phenolphthalein Reagent (2246 - E) to the sample. If the solution remains colourless proceed directly to step 3. If the sample turns red, add Sulphuric Acid (6090 - E) one drop at a time until the red colour disappears. Then proceed to step 3.
3. Add three drops of the Chloride Reagent No.1 (4504 - E) to the sample in the Test Tube. Insert the Test Tube Cap and shake to mix. A yellow colour will result.
4. Fill Titrator with the Chloride Reagent No. 2 (4505 - H) to the 'Zero' mark in the Test Tube Cap. Then add to sample drop by drop, shaking gently, until the yellow colour is permanently changed to pink / brown.
5. Result is obtained in p.p.m. Chloride by multiplying Titrator reading by ten.
