Total Residual Chlorine (TRC) is the total of free available residual chlorine and combined (bound) residual chlorine. The amount of measurable chlorine remaining after treating water with chlorine i.e. amount of chlorine left in water after the chlorine demand has been satisfied
The reagent used in determining free and total chlorine residual for disinfection of drinking water. The chemical name of the reagent is NN Diethyl-p-Phenylenediamene.

Technically no. Your total chlorine reading would include all forms of chlorine, which we tend to lump into to basic categories, Free and combined. If you get readings that show that the free amount is higher then total, I would suggest a retest. If you are still getting the same result, I would try another test or different reagents. I'm sure there might be something that could give you false results and that might be what id happening in this case. Actually it can happen because it happened to me today i saw it happen that the free chlorine was 2.49 and after the 2 minute waiting period the test was 0.33 and the sample was visibly less pink than when the DPD 1 was tested, there has to be some reason for this or some way to fix it as if we are using the same reagents for other samples and it is working for those then this must mean that there is something wrong with the water i a, testing and not the tablets i am testing with! The total reading after time will drop if the residual level is high enough and there is not enough DPD. Hach recommends for using a 5 ml sample instead of 10 ml and 2 power pillows instead of 1. This gives four times the DPD to do the analysis. With very high levels you can see a flash of dark color and then go to clear as the chlorine bleaches the color from the DPD. The addition of extra DPD overcomes the bleaching effect.
You can test the water for chlorine levels using a pool water test kit. Mains water typically contains chlorine, which is used to disinfect the water. If the water shows a chlorine residual, it is likely mains water.
The total charge of chlorine is -1. Chlorine typically forms an anion with a charge of -1 by gaining one electron to achieve a stable electron configuration.
Total residual oxidants include all chlorine species present in water, which includes both free chlorine and combined chlorine. Total residual chlorine specifically refers to the amount of chlorine left in water after a certain contact time. In summary, total residual oxidants encompass total residual chlorine but also include other chlorine species.
The total residual chlorine in seawater can be affected by various factors such as sunlight exposure, temperature, pH levels, and the presence of organic matter. Sunlight can break down chlorine, leading to lower residual levels. Higher temperatures can also decrease residual chlorine, as can higher pH levels. Presence of organic matter can also consume chlorine, affecting the total residual levels in sea water.
Residual chlorine refers to the amount of chlorine that remains in water after it has been treated. It is important for maintaining water quality by ensuring that harmful pathogens are destroyed and that the water remains safe for consumption. Monitoring residual chlorine levels is a common practice in water treatment facilities to ensure that water is properly disinfected.
Chlorine residual refers to the amount of chlorine remaining in water after the disinfection process. It is an important measure to ensure that water is safe for consumption by preventing the growth of harmful bacteria and pathogens. Chlorine residual levels are typically monitored to ensure they meet regulatory standards for water quality.

Combined chlorine is when the chlorine molecule has attached itself to other molecules in water. In other words it has "combined" with something else in the water. Those could be iron, manganese, ammonia or other things depending on the source water. Free chlorine is the molecules that are "free" in the water to do the disinfection.

Adding an indicator in the middle of a titration of residual chlorine helps to visually identify the endpoint of the reaction. The indicator changes color at the equivalence point, indicating that all the chlorine has reacted. This helps to determine the amount of titrant required, making the titration more accurate and precise.
Chloramines can be calculated by the formula: Chloramines = Total Chlorine - Free Chlorine. Total chlorine is the sum of free chlorine and combined chlorine (chloramines). By subtracting the free chlorine level from the total chlorine level, you can determine the amount of chloramines present in the water.
Chlorotex is a test designed for residual chlorine in water, not ozone. To measure residual ozone in water, specific analytical methods like ozone analyzers or oxidation-reduction potential (ORP) meters would be more appropriate. These methods are designed to specifically measure the presence of ozone in water.
Yes, just install the chlorine generator and add the salt. Your new system will replace the need for residual chlorine.
