Just wanna make sure, if i did it correct or not.
Cl2 + 2NaBr --> Br2 + 2NaCl
(0)---(+1)--(-1)---(0)------(+1)(-1)
So Cl2 loss = oxidation
Br2 Gain = Reduction
Am I correct ? Thanks
I don't know what your definition is of oxidation/reduction. Your answeres ae not right.
My definition is that oxidation is the loss of electrons and reductin is the gain of electrons.
You have the oxidation states marked correctly. So Cl goes from 0 on the left to -1 on the right. That is a gain of electrons which makes it reduced (and it is the oxidizing agent).
Cl2----->2NaCl=reduction
2NaBr---->Br2=oxidation
Yes, you are correct! In the given chemical equation, chlorine gas (Cl2) is being reacted with sodium bromide (NaBr) to produce bromine gas (Br2) and sodium chloride (NaCl).
To determine if there is an oxidation or reduction occurring, you can assign oxidation states to each element in the equation. The oxidation state is a measure of how many electrons an atom has gained or lost.
In this reaction:
- Chlorine (Cl) has an oxidation state of 0 on the left side of the equation since it exists as Cl2, where each chlorine atom has an oxidation state of 0.
- Sodium (Na) has an oxidation state of +1 in both NaBr and NaCl, as it usually loses one electron to have a charge of +1.
- Bromine (Br) has an oxidation state of -1 in NaBr, as it typically gains one electron to have a charge of -1.
- Bromine (Br) has an oxidation state of 0 on the right side of the equation since it exists as Br2, where each bromine atom has an oxidation state of 0.
By comparing the oxidation states of the elements before and after the reaction, we can determine the oxidation and reduction.
In this case:
- Chlorine (Cl) undergoes a decrease in oxidation state from 0 to -1 in NaCl, which means it has lost electrons and been oxidized. This is the oxidation process.
- Bromine (Br) undergoes an increase in oxidation state from -1 to 0 in Br2, which means it has gained electrons and been reduced. This is the reduction process.
So, your conclusion is correct. Chlorine (Cl2) undergoes oxidation, while bromine (Br2) undergoes reduction in this reaction.
