redox reaction
a chemical reaction involving both oxidation and reduction
oxidation symptoms
oxidation occurs in a chemical reaction, signs of oxidation are
gain of oxygen
loss of hydrogen
loss of electron
increase in oxidation state
reduction symptoms
reduction occurs in a chemical reaction, signs of reduction are
loss of oxygen
gain of hydrogen
gain of electron
decrease in oxidation state
In a redox reaction AGENTS
The oxidizing agent gains electrons and is reduced, when react gain electron and gets reduced
The reducing agent loses electrons and is oxidized. when react lose electron and gets oxidized
oxidation and reducing agents
oxidation agents and reducing agents are substances involved in (reduction - oxidation) reactions
oxidation state
a number assigned to an element in a substance to show the degree of oxidation
(valency charge)
oxidizing agents (oxidants)
causes oxidation in another substance, and reduces itself
reducing agents -
causes reduction in another substance and oxidizes itself
electron transfer
a transfer of electrons in a chemical reaction is a redox reaction
oxidation state on atoms
oxidation state to an atom with a charge means there's a state of oxidation present
oxidation state on atoms examples
na^+ has an oxidation state of +1
cl2 has an oxidation state of 0
cl^- has an oxidation state of -1
