Mar 03, 2012· Step 7: Crush Your Potassium Nitrate. Pour out the remaining liquid in the container without pouring out your crystals. Wait until the crystals have dried. Even though they look like rocks, in reality, they have the consistency of slush. Let the open container sit in a well-ventilated area. When dry, crush the crystals into a very fine powder.
Problem #2: Potassium dichromate is used to titrate a sample containing an unknown percentage of iron. The sample is dissolved in H 3 PO 4 /H 2 SO 4 mixture to reduce all of the iron to Fe 2+ ions. The solution is then titrated with 0.01625 M K 2 Cr 2 O 7, producing Fe 3+ and Cr 3+ ions in acidic solution. The titration requires 32.26 mL of K 2 Cr 2 O 7 for 1.2765 g of the sample.
Unfortunately, potassium permanganate is not very soluble either, so this is not advantageous for making it.
