How do I determine how many moles of KMnO4 it takes to neutralize C2O4-?
You can't without knowing how much of the oxalate you have; however, you may find the ratio of oxalate to permanganate from the below.
2MnO4^- + 5C2O4^2- + H^+ ==> 10CO2 + 2Mn^2+
The above equation isn't completely balanced but you may complete it if you wish; however, the redox part (the part that matters in this equation) IS balanced. To work the problem balancing the redox part is all that is required. But be careful, some profs won't let you get away with that.
Use the coefficients in the above equation to convert mols C2O4^2- to mols MnO4^-
Well, my chemistry-challenged friend, determining the number of moles needed to neutralize C2O4- with KMnO4 is a bit like trying to count the number of clowns in a circus. It can get pretty confusing! You see, the reaction between KMnO4 and C2O4- is a redox reaction, where electrons are transferred from one compound to another. To figure out the mole ratio, you will need to balance the equation first. Once you've done that, the coefficients in front of each compound will give you the number of moles needed to neutralize C2O4-. Good luck, and remember, don't let those elusive moles clown around too much!
To determine how many moles of KMnO4 (potassium permanganate) are required to neutralize C2O4- (oxalate ion), you need to consider the balanced chemical equation representing the neutralization reaction.
The balanced chemical equation is as follows:
2KMnO4 + 5C2O4- + 16H+ → 2Mn2+ + 10CO2 + 8H2O + 2K+
From the balanced equation, you can see that 2 moles of KMnO4 react with 5 moles of C2O4-.
Therefore, you would need a ratio of 2 moles KMnO4 : 5 moles C2O4-.
To determine how many moles of KMnO4 it takes to neutralize C2O4-, we need to use stoichiometry. Stoichiometry is a way of relating the amounts of substances involved in a chemical reaction.
To start, we need to know the balanced chemical equation between KMnO4 and C2O4-. Let's assume the balanced equation is:
2 KMnO4 + 5 C2O4- -> 2 MnO2 + 10 CO2 + K2O
According to the equation, 2 moles of KMnO4 react with 5 moles of C2O4-. We can use this information to set up a stoichiometric ratio.
So, the stoichiometric ratio is 2 moles of KMnO4 : 5 moles of C2O4-.
If you have the number of moles of C2O4- available, you can use this ratio to calculate the number of moles of KMnO4 required.
Here's an example:
Suppose you have 4 moles of C2O4-. To find out how many moles of KMnO4 are required, we use the stoichiometric ratio:
(4 moles C2O4-) x (2 moles KMnO4 / 5 moles C2O4-) = 1.6 moles KMnO4
Therefore, it would take 1.6 moles of KMnO4 to neutralize 4 moles of C2O4-, based on the balanced chemical equation.
Remember to always make sure the chemical equation is balanced and use the correct stoichiometric ratio for accurate calculations.
