In the ocr book there is an example of "redox in terms of oxidation numbers" (page 51) and the chemical equation is Cu + 2AgNO3 -> 2Ag + Cu(NO3)2.So Cu has actually an oxidation number of 0 because all aspects have one Ox Num of 0.In the book it states 2Ag has an oxidation Num that +1 in 2AgNO3 but an oxidation variety of 0 for 2Ag in the assets of the reaction. Likewise Cu bechathamtownfc.netmes +2 because that Cu(NO3)2. Have the right to someone please explain how a redox reaction occurs v oxidation numbers and how to understand the oxidation variety of a chathamtownfc.netmpound choose 2Ag.Thank you.

(Original write-up by ineedthosegrades) In the ocr publication there is an example of "redox in terms of oxidation numbers" (page 51) and the chemistry equation is Cu + 2AgNO3 -> 2Ag + Cu(NO3)2.So Cu has actually an oxidation variety of 0 due to the fact that all aspects have an Ox Num that 0.In the book it says 2Ag has an oxidation Num the +1 in 2AgNO3 however an oxidation number of 0 because that 2Ag in the assets of the reaction. Likewise Cu bechathamtownfc.netmes +2 for Cu(NO3)2. Have the right to someone please define how a oxidation reaction occurs v oxidation numbers and also how to know the oxidation variety of a chathamtownfc.netmpound choose 2Ag.Thank you.
Redox is all around gain and loss that electrons:O xidation ns sL ossR eductionI sG ainOILRIGThe silver changes from one oxidation state of +1 chathamtownfc.netme 0Hence that has got one an unfavorable charge, because of this it has been reduced.The chathamtownfc.netpper transforms from 0 chathamtownfc.netme +2, because of this it has lost two electrons. It has been oxidised.

(Original write-up by charchathamtownfc.net) redox is all around gain and also loss the electrons:O xidation ns sL ossR eductionI sG ainOILRIGThe silver transforms from one oxidation state the +1 to 0Hence the has obtained one negative charge, because of this it has actually been reduced.The chathamtownfc.netpper alters from 0 chathamtownfc.netme +2, because of this it has actually lost 2 electrons. It has been oxidised.
Thanks that provides sense. But how would certainly you rechathamtownfc.netgnize that silver has an oxidation number of +1 in the beginning?

(Original short article by ineedthosegrades) thanks that provides sense. But how would certainly you understand that silver has actually an oxidation variety of +1 in the beginning?
Rules that oxidation numbers:1. The sum of every oxidation numbers in a types equals the fee on the types (hence aspects are chathamtownfc.netnstantly zero).2. For straightforward ions, the oxidation number is the same as the ionic charge.3. In any varieties the most electronegative atom takes a an adverse oxidation state4. Hydrogen is always +1 (except when dominance 3 applies)5. Oxygen is always -2, except for peroxides (-1) and rules 1 & 3.AgNO3 is ionic therefore Ag+ has an oxidation number of +1 (rule 2)
