Answer:
Such reaction's kinetics is slow.
Explanation:
Hello,
In this case, in quantitative analysis when using sodium it is mandatory to use a glass buret for titrations as it is accurate in terms of measuring volume; however, when sodium hydroxide is in contact with the glass, a very slow rate is present when it reacts with the silicates in the glass, forming sodium silicate, such rate is in the order of 1.3×10⁻⁴ and 4.3 × 10⁻⁴ g/(m² s). In this manner, as an experiment does not take more than 10 minutes (typical titrations) the time is not enough to for a considerable amount of sodium silicate, that is why its use is widely enforced.
Best regards.
The balanced redox equation of the reaction is given below:
- I⁻ + 2 MnO₄ + H₂O → IO₃⁻ + 2 MnO₂ + 2 OH⁻
The oxidizing agent is MnO₄ while the reducing agent is I⁻.
<h3>What are redox equations?</h3>
Redox equations are equations in which oxidation and reduction reactions occur together.
Redox reactions can take place in alkaline or acidic mediums.
The balanced redox equation of the reaction is given below:
- I⁻ + 2 MnO₄ + H₂O → IO₃⁻ + 2 MnO₂ + 2 OH⁻
The oxidizing agent is MnO₄ while the reducing agent is I⁻
In conclusion, a balanced redox equation is one in which the atoms and the change in oxidation state is equal on both sides of the reaction.

One decimal place.
The reading in graduated cylinder is marked after every 1 mL and that of pipette at every 0.1 mL. If same amount of water is taken from both the containers. The sum of volume of water will take the minimum decimal places. Precise value of volume is calculated using pipette as it has markup after every 0.1 mL, the lowest decimal place will be 1 decimal place (0.1).
It should be chloride C12
