Also, electrochemical treatment is used for polishing, for example aluminium and stainless steel. Electricity helps to get hydrogen from water, aluminium and alkaline metals are synthesised using electrolysis. Also, sodium chlorate-KClO3, found in matches and pyrotechnical mixtures, is prepared via electrolysis. Metal activity row K Ca Na Mg Al Zn Cr Fe Ni Sn Pb H2 Cu Hg Pt Au predicts which metals react with acids, evolving hydrogen, and afore metals push away rear metals. </p> <p align="center" style="margin-top: 12; margin-bottom: 12"> <a style="cursor:pointer" onclick="window.open('http://www.chemicum.com/?vid=8&lan=EN','mywindow','width=860,height=642')"><img width="241",height="180", src="http://www.chemicum.com/img/Electrolysis_of_water.jpg"/></a> <a style="cursor:pointer" onclick="window.open('http://www.chemicum.com/?vid=9&lan=EN','mywindow','width=860,height=642')"><img width="241",height="180", src="http://www.chemicum.com/img/Changes_in_pH_during_water_electrolysis.jpg"/></a> <a style="cursor:pointer" onclick="window.open('http://www.chemicum.com/?vid=49&lan=EN','mywindow','width=860,height=642')"><img width="241",height="180", src="http://www.chemicum.com/img/Deposition_of_copper_on_iron.jpg"/></a> <a style="cursor:pointer" onclick="window.open('http://www.chemicum.com/?vid=50&lan=EN','mywindow','width=860,height=642')"><img width="241",height="180", src="http://www.chemicum.com/img/Deposition_of_mercury_on_copper.jpg"/></a> <a style="cursor:pointer" onclick="window.open('http://www.chemicum.com/?video=100&lan=EN','mywindow','width=860,height=642')"><img width="241",height="180", src="http://www.chemicum.com/img/Electrochemical_deposition_of_copper.jpg"/></a> <iframe width="241" height="136" src="https://www.youtube.com/embed/eGnPQtai0og?rel=0" frameborder="0" allowfullscreen></iframe> </p> <p align="center"><fb:like href="http://www.chemicum.com/electrochemistry" send="false" width="450" show_faces="false"></fb:like></p> </body> </html>
