During standardization of permanganate solution using sodium oxalate, can the titration between Mno4- and C2o42- at 25degree celcius be perform? state the reasons.
To determine whether the titration between MnO4- (permanganate) and C2O42- (oxalate) can be performed at 25 degrees Celsius, we need to consider the factors that can affect the titration reaction. Here are a few key points to consider:
1. Reaction temperature: One of the crucial factors in any titration is the temperature of the reaction. The rate of the reaction can vary with temperature, and it can influence the accuracy and precision of the results. The standard temperature for most chemical reactions, including titrations, is 25 degrees Celsius. So, performing the titration at this temperature is generally acceptable.
2. Reaction kinetics: The reaction between MnO4- and C2O42- is a redox reaction, where permanganate oxidizes oxalate. At higher temperatures, this reaction can become faster, making it difficult to control the reaction rate during the titration. However, at 25 degrees Celsius, the reaction proceeds at a reasonable rate, allowing for accurate and manageable titration.
3. Stability of solutions: Both the permanganate and oxalate solutions need to be stable during the titration. Permanganate solutions are generally stable within a specific pH range, typically around pH 1-2. Oxalate, on the other hand, is relatively stable in most conditions. At 25 degrees Celsius, both solutions are expected to remain stable, maintaining their reactivity throughout the titration.
In summary, the titration between MnO4- and C2O42- can be safely performed at 25 degrees Celsius. The reaction kinetics and solution stability are suitable for accurate and controlled titration. However, it's always essential to consult specific experimental protocols or guidelines as they may suggest different temperatures or conditions based on the specific requirements of the experiment.
