How prepare 0.1 n k2cr2o7?
To prepare a 0.1 N solution of K2Cr2O7 (potassium dichromate), you would need to dissolve 4.903 grams of K2Cr2O7 in enough water to make 1 liter of solution. Weigh out the exact amount of K2Cr2O7 using a balance, then dissolve it in water and make up the volume to 1 liter. This will give you a 0.1 N solution of K2Cr2O7.
How do you Prepare 0.02 N potassium permanganate solution?
To prepare a 0.02 N potassium permanganate solution, you would need to dissolve 1.58 grams of potassium permanganate (KMnO4) in 1 liter of distilled water. This will give you a solution with a molarity of 0.02 N. Remember to wear appropriate personal protective equipment when handling potassium permanganate, as it can be harmful.
Why you can use 4.9035 g K2Cr2O7 to prepare 0.1 n solution?
To prepare a 0.1 N solution of K2Cr2O7, you need to calculate the molar mass of K2Cr2O7 and use the formula for normality. By dividing the given weight by the molar mass, you can determine the number of moles present, and then calculate the normality using the volume of the solution.
How do you prepare standard solution of potassium dichromate to compare icteric index of serum?
for preparing 0.1 normal solution of potassium permanganate you have to disssolve 3.16 g potssium permangnate in 1L water bt in alkaline or neutral medium reactions of potassium permanganate is different and Mn gains 3 electrons in redox reaction,so far alkaline medium redox titration equivalent wt of KMnO4 will be 158\3=52.6.so far,0.1 N KMnO4 in alkaline medium redox titration dissolve 5.26 g in 1L sol.
How do you prepare 1 N ferrous ammonium sulphate?
To prepare 1 N ferrous ammonium sulfate solution, dissolve 392.15 g of the compound in distilled water and dilute to 1 L. This will yield a solution with a concentration of 1 N.
How do you make up 1.5 N Potassium Dichromate in 1 liter solution?
- Dry potassium dichromate (standard certified quality, from NIST - SRM 136f or from another supplier), using a platinum dish or crucible. - Follow the mode of drying (generally 1 hour at 120 0C in an oven) indicated by the supplier. Place the potassium dichromate in an exsicator. - Prepare a volume of demineralized or distilled water - Weight 73,546 25 g potassium dichromate in a platinum dish calcined to a constant weight; apply a correction for the flotability of the air and the purity of the dichromate. Use a metrologically checked microbalance. - Place carefully the potassium dichromate in a 1 000 mL volumetric flask, dried and washed - Add about 900 mL water - Place the volumetric flask in a thermostat at 20 0C; after approx. 30 min add the water exactly to the mark. - Stirr the content of the volumetric flask; place a clear label on the flask (concentration, material, date of preparation, operator's name).

How do you prepare 0.1 n alcoholic potassium hydroxide solution?
To prepare a 0.1 N alcoholic potassium hydroxide solution, you would mix potassium hydroxide pellets with a calculated amount of alcohol, such as ethanol, in a specific volume to achieve the desired concentration. It is important to handle potassium hydroxide with care due to its corrosive nature, and protective equipment should be worn during preparation. After mixing the components thoroughly, the solution should be standardized using a suitable acid to verify its concentration.
