What is the reaction between mno4- and c2o42- and is there a colour change in this reaction?
The reaction between MnO4- (permanganate ion) and C2O42- (oxalate ion) is a redox reaction. In this reaction, permanganate ion acts as the oxidizing agent, while oxalate ion acts as the reducing agent.
The balanced chemical equation for this reaction is as follows:
2MnO4- + 5C2O42- + 16H+ → 2Mn2+ + 10CO2 + 8H2O
In this reaction, the permanganate ion is reduced to Mn2+ ions, and the oxalate ions are oxidized to carbon dioxide (CO2).
Now, let's talk about the color change in this reaction. Initially, the solution containing permanganate ion (MnO4-) is purple in color. As the reaction progresses, the permanganate ion is consumed, resulting in a color change to colorless. On the other hand, the formation of Mn2+ ions does not have any specific color, so the overall color change is from purple to colorless.
Remember, the color change may not be instantaneous and can take some time to fully occur.
The reaction between MnO4- (permanganate ion) and C2O42- (oxalate ion) is a redox reaction. Permanganate ion acts as the oxidizing agent, while oxalate ion serves as the reducing agent.
To determine the products of the reaction, you need to balance the equation. The balanced equation for the reaction between MnO4- and C2O42- is as follows:
2MnO4- + 5C2O42- + 16H+ → 2Mn2+ + 10CO2 + 8H2O
In this reaction, permanganate ion gets reduced to manganese ion (Mn2+), and oxalate ion gets oxidized to carbon dioxide (CO2). The presence of hydrogen ions (H+) in the reaction assists in balancing the charges.
Regarding the color change, there is a noticeable color change during this reaction. Permanganate ion (MnO4-) is intensely purple, while manganese ion (Mn2+) is pale pink. Therefore, as the reaction proceeds, you will observe a color change from purple to pink.
Please note that accurately observing the color change might require reference to a color chart or comparison against a known standard color.
