How many grams of potassium are present in 21.6 g of K2Cr2O7?
To find the amount of potassium in K2Cr2O7, calculate the molar mass of K2Cr2O7 first. The molar mass of K2Cr2O7 is 294.2 g/mol. Potassium accounts for 239.1 g/mol = 78.2 g/mol in K2Cr2O7, so in 21.6 g of K2Cr2O7, there are 21.6 g * (239.1 g/mol / 294.2 g/mol) = 5.77 g of potassium.
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.
What is the compound for K2Cr207?
The compound K2Cr2O7 is potassium dichromate. It is a bright orange solid commonly used in laboratories as an oxidizing agent and for various chemical reactions.
What is the name of K2Cr2O7?
Potassium dichromate
What is difference between K2Cr2O7 and K2Cr2O4?
K2Cr2O7 is potassium dichromate, while K2Cr2O4 is potassium chromate. K2Cr2O7 is an orange-red compound used as an oxidizing agent, while K2Cr2O4 is a yellow compound. K2Cr2O7 tends to be more powerful as an oxidizing agent compared to K2Cr2O4.
How do you make 0.25N K2Cr2O7 solution?
To prepare a 0.25N K2Cr2O7 solution, you would dissolve 12.43 grams of K2Cr2O7 in enough water to make 1 liter of solution. This will give you a molarity of 0.25N for potassium dichromate (K2Cr2O7) in the solution.
