How do you prepare double distilled water and what is the role of adding potassium permanganate?
What else can I help you with?
Will propene react with potassium permanganate?
Yes, propene can react with potassium permanganate through a process called oxidation. This reaction results in the formation of a diol (1,2-propanediol) by adding hydroxyl groups to the carbon-carbon double bond in propene.
Why does the color of potassium permanganate not disappear when excess of ethanol is added to it?
The color of potassium permanganate does not disappear when excess ethanol is added because ethanol is unable to fully reduce the permanganate ion (MnO4-) to colorless manganese dioxide (MnO2). Ethanol is a weak reducing agent and is not capable of completely reducing the permanganate ion in this reaction. Additionally, the reaction between potassium permanganate and ethanol is not stoichiometric, meaning that there is an excess of one of the reactants, which can also contribute to the color persisting.
How Potassium permanganate is use for purifying drinking water?
Potassium permanganate can be used for purifying drinking water by acting as a strong oxidizing agent to eliminate organic compounds, iron, and other impurities. By adding a small amount of potassium permanganate to water, it can help remove bacteria and odors, making the water safer to drink. However, it is important to use the correct dosage to avoid any negative health effects from excess intake of potassium permanganate.
How can we prepare potassium chromate?
To prepare potassium chromate, start by dissolving potassium dichromate in water and then adding potassium hydroxide to adjust the pH. The solution is then heated to evaporate water, leaving behind potassium chromate crystals. Purify the crystals by recrystallization to obtain pure potassium chromate.
How to prepare 250ml of a 2m solution of potassium chloride?
To prepare 250ml of a 2M potassium chloride solution, measure out 17.8g of potassium chloride and dissolve it in water to make a total volume of 250ml. Make sure to stir the solution well to ensure the potassium chloride is completely dissolved. Then, adjust the final volume to exactly 250ml by adding more water if needed.

How to get the balance equation for a redox reaction of oxalic acid plus potassium permanganate?
To balance the redox reaction between oxalic acid (H2C2O4) and potassium permanganate (KMnO4), first write down the unbalanced equation. Then balance the atoms of each element on both sides of the equation, starting with elements that are not hydrogen or oxygen. Next, balance the oxygen atoms by adding water molecules. Finally, balance the hydrogen atoms by adding H+ ions. Count the charges on each side and balance them by adding electrons.
Why is it important to leave the water to become completely still before potassium permanganate crystals can be added?
if the water is moving, the spreading of the molecules has the aid of the moving water and the experiment will become meaningless
If a cell in a wet cell battery goes dry can it be revived by adding distilled water?
yes with distilled water
How can we prepare litmus solution in lab?
To prepare a litmus solution in the lab, you can dissolve powdered litmus in distilled water to create a purple solution. Stir the mixture well to ensure the litmus is fully dissolved. Adjust the concentration of the solution by adding more litmus or water as needed.
Explain how you would prepare a saturated solution of potassium nitrate in water?
Add potassium nitrate to distilled water while stirring continuously; stop adding potassium nitrate once the chemical becomes saturated and stops dissolving in the water. Filter the solution into an evaporating dish and measure the temperature of the solution. Measure the temperature and carefully heat the solution under low heat. Weigh the potassium nitrate to determine its solubility. You should find that approximately 36 g of potassium nitrate can be dissolved in 100 ml of water at room temperature (25 degrees Celsius). santosh kumar.batchu santoshkumar@gmail.com
Why do you have to heat up the solution of oxalic acid after adding sulphuric acid for the titration with permanganate?
To act as a catalyst
