oxidation question your wrong....
its O to -3 reduction as Ph3 has +3 hydrogen so P must be -3
O to +1 oxidation

I don't know about the exam - certain Ive lost at least 2 marks and think another 3 on here.On the structure of KCL I put a + and - charges on the circles so they are attracting each other but i labelled a positive circle and said positive potassium ion and did likewise for chlorine ? Would I get both marks ?
