If you skip adding sulphamic acid in the chemical oxygen demand (COD) procedure, nitrites present in the sample may interfere by being oxidized, leading to an overestimation of the COD result. Sulphamic acid is used to neutralize nitrites and prevent this interference.
To prepare a PPM (parts per million) solution, you will need to follow a specific procedure. PPM is a unit of concentration that represents the ratio of one part of a substance to one million parts of the solution. It is commonly used in various fields such as chemistry, biology, environmental science, and industrial applications. Here is a step-by-step guide on how to prepare a PPM solution: 1. Determine the desired concentration: The first step is to determine the desired concentration of the solution in parts per million. This will depend on the specific application or experiment you are conducting. 2. Calculate the amount of solute needed: Once you have determined the desired concentration, you need to calculate the amount of solute required to achieve that concentration. This calculation involves considering the molecular weight or molar mass of the solute and the volume of the solution you want to prepare. 3. Weigh the solute: Using an analytical balance, weigh the calculated amount of solute accurately. It is crucial to ensure precise measurements for accurate results. 4. Dissolve the solute: Transfer the weighed solute into a suitable container, such as a beaker or flask. Add a small amount of solvent (usually water) to dissolve the solute completely. Stir gently until all particles are dissolved. 5. Add more solvent: Once the solute is dissolved, add more solvent to reach the desired volume of your solution. The volume will depend on your specific requirements and experimental setup. 6. Mix thoroughly: After adding the solvent, mix the solution thoroughly using a stir rod or magnetic stirrer. This ensures uniform distribution of the solute throughout the solution. 7. Verify concentration: To verify the concentration of your PPM solution, you can use various analytical techniques such as spectrophotometry, titration, or other appropriate methods depending on your specific application. It is important to note that preparing PPM solutions requires careful attention to detail and accurate measurements. Any errors in weighing or measuring can significantly affect the concentration and validity of your solution. In conclusion, preparing a PPM solution involves determining the desired concentration, calculating the amount of solute needed, weighing the solute accurately, dissolving it in a suitable solvent, adding more solvent to reach the desired volume, mixing thoroughly, and verifying the concentration using appropriate analytical techniques.

In the context of Chemical Oxygen Demand (COD) determination, using distilled water serves as a control or blank in the testing process. Here are more details: 1. **Purity:** Distilled water is devoid of impurities and organic matter. Its purity ensures that any oxygen demand observed during the test is attributed solely to the substances present in the sample, allowing for an accurate measurement of the sample's COD. 2. **Baseline for Calibration:** Distilled water establishes a baseline for the COD test. By measuring the oxygen demand in the absence of any organic or inorganic contaminants, you create a reference point for zero COD. This baseline helps calibrate the apparatus and correct for any background oxygen demand inherent in the testing system. 3. **Standardization:** Distilled water provides a standardized reference for comparing results across different samples and experiments. It serves as a control to ensure consistency and reliability in COD measurements. 4. **Interference Elimination:** The use of distilled water eliminates the interference from background substances that might contribute to the oxygen demand. This is essential for accurately attributing the measured COD to the constituents in the sample being tested. In summary, distilled water acts as a clean reference, allowing for precise COD measurements by providing a clear distinction between the oxygen demand originating from the sample and any potential interference from the water itself.
