adsorption‚ coagulation‚oxidation and precipitation were commonly used to treat dyes in wastewater effluent. Among these treatments‚ advanced oxidation processes (AOPs) had been widely investigated by researchers around the world and it considered as a promising treatment method to destroy these organic pollutions in wastewater. One of the AOPs so called wet air

LAB 3: QUALITATIVE ANALYSIS Part 2- ANIONS Sameera Feroz Butt Lab Partner: Ram Soni Thursday January 30‚ 2014 Leilani Morales CHEM1131-02 OBJECTIVE The objective of this experiment was to use qualitative analysis to determine the chemical characteristics of four known anions by systemic confirmatory testing. The chemical characteristics observed were to be used to identify an unknown sample. Sulphuric acid was to be added to a carbonate solution and an effervescent reaction would

Redox stands for reduction-oxidation‚ and are electrochemical processes involving electron transfer to or from a molecule or ion changing its oxidation state. This reaction can occur through the application of an external voltage or through the release of chemical energy. Oxidation and reduction Oxidation and reduction describe the change of oxidation state that takes place in the atoms‚ ions or molecules involved in an electrochemical reaction. Formally‚ oxidation state is the hypothetical

The purpose of Experiment 36 is to identify the anions present in an unknown solution based on the chemical reactions with various chlorides. In this experiment‚ Pb2+ was present in the unknown solution‚ while the presence Hg22+ is in doubt‚ and Ag+ is absent. To begin‚ the first part of the experiment involved analyzing the results from the experiment with the solution with equal volumes of AgNO3‚ Pb(NO3)2‚ and Hg2(NO3)2. Based on the results and observations obtained from the tests with the stock

Lanthanides and Actinides The lanthanides and the actinides make up the f block of the periodic table. The lanthanides are the elements produced as the 4f sub level is filled with electrons and the actinides are formed while filling the 5f sub level Some significant similarities and differences between lanthanides and actinides are observed. The two rows that are generally placed underneath the main periodic table are called the lanthanides series and the actinides series. These two rows are produced
