Determination Of Nitrate Ion In Treated Wastewater Effluent Lab Report

Determination Of Nitrate Ion In Treated Wastewater Effluent - Lab Report Example The possible causes of errors may result from wrong or inaccurate readings made in the spectrophotometer. The spectrophotometer is in use to measure the intensity of red color produced when nitrate reacts with the acid, sulfanilic and N- naphthyl ethylenediamine. The lack of calibration of the equipment causes errors in results. The equipment may record a reading higher or below the one expected. Errors result from measurements done by using flasks and pipettes. When experimenters fail to monitor the readings properly, the final value of concentration will be affected.    For example, observers of volumetric readings should look at the lower meniscus to prevent these errors. Such errors will affect dilution and dissolving of solids in solutions (Woody 12).   The possible causes of errors may result from wrong or inaccurate readings made in the spectrophotometer.
