Hello I'm trying to use sodium nitrate + sulfuric acid to make 70% nitric acid. I understand the formula is a 2-1 mole = 1-2 mole nitric. But I can not get this to turn out right. If I add 1700 grams of sodium nitrate and 850 grams of sulfuric acid and 550 grams of water this should give me almost 2 liters of nitric acid but it's not.

(2) For the equivalent of 50/50, 70% nitric, use the 50% acid and add 27%, by volume, extra water. For example, you could add 270ml of water to 1000ml of 50% nitric. To make up exactly 1 liter of 50/50, combine 787ml of 50% nitric with 213ml of distilled water. By the way, gold4mike, when you dilute 70% nitric 50/50, you end up with 41% nitric.

At 20C, the specific gravity of 52% nitric is 1.3219. Therefore, 1 liter weighs 1321.9g. Multiply 1321.9 x .52 and this gives 687g of nitric per liter of 52% nitric. Do the same for the 70% and you come up with 989g/liter. Therefore, 36 baume' nitric is about 687/989 = about 69.5% as strong as 42 baume nitric.

In that respect, I'd like to take a shot at this: Try first more 50/50 nitric acid/distilled water. Heat it to 68C for an hour. Let it cool and settle to room temperature. Carefully decant the solution and save it for silver recovery. Repeat this process with concentrated nitric acid. Save the solution for possible palladium.
