The video tutorial explains how to determine the oxidation states of elements in potassium thiocyanate (KSCN). It begins by identifying KSCN as a neutral compound, meaning the sum of oxidation numbers is zero. Potassium, being in group one, has a +1 oxidation state. The video then focuses on the thiocyanate ion (SCN), where electronegativity is used to assign oxidation states: nitrogen is -3, sulfur is -2, and carbon is calculated to be +4. The tutorial concludes by verifying the sum of oxidation numbers equals zero, confirming the neutrality of KSCN.
