True rust removal by a chemist - boosting the performance of white vinegar by electrolysis

The main rust removal component active in white vinegar is acetic acid, which makes up 3-7 % of the white vinegar. This low concentration is very inefficient for the rust removal as an acid content but it's performance can be dramatically boosted and improved with electrolysis. in this video it is demonstrated how to increase the performance of white vinegar and the fundamental requirements for having an effective rust removal process in only one hour. The relevance of having two conductors in the electrolyte is explained and demonstrated, and the conductivity of the conductors is compared when thick heavy rust is sealing one of the electrodes. Rust is an inorganic oxide that poorly conducts electricity. The inorganic oxide called rust is also named iron oxide, which can includes many different compositions including FE2O3, FeOH3, FeOOH2 etc. The insulating capacity of these sub phases is determined by the state of the rust and the presence of water inside the rust. For better rust dissolving properties of the acid, a stronger acid with lower pKa values than acetic acid, the acid in white vinegar, is required, see further: video ‘True rust removal by a chemist - acids compared’. Ättika innehåller ättiksyra, vilket är en miljövänlig syra som kan användas för att sänka pH värdet på en vattenlösning för rostborttagning med elektrolys. Rosten isolerar metallen under och i videon beskrivs hur viktigt det är att man kopplar strömkällan till den rena metallen. Gasen som avges under elektrolysen är vätgas, vilket betyder att reaktionen måste ske under väl ventilerade förhållanden. Om man önskar snabbare rostborttagning så kan man använda starkare syror som lättare löser ut järnet i rosten i lösning.
