Found some spelling errors... such as the EDTA, it supposed to be "ethylenediaminetetraacetic acid" instead of "ethylenediametetraacetic acid"...Overall the video is pretty helpful!
Being a teacher you could not write the structure of EDTA from your memory. It is a shame. First write the structure of ethylene (H2C = CH2). Then write ethylenediamine by adding two NH2 groups in the double bond (H2N - CH2 - CH2 - NH2). Then substitute four H of two - NH2 groups by four - CH2 - COOH groups (acetic acid). Voila. It's easy; not as hard as Physics.
