What is the difference between nitric acid and fuming nitric acid
The main difference between fuming nitric acid crystals and concentrated nitric acid is that, unfortunately, fuming nitric acid produces its own colorless, yellowish, or brownish smoke, as concentrated nitric acid does not normally produce smoke. but the latter very high concentration of this uric acid can produce a breathtaking off-white smoke.
What is the difference between concentrated nitric acid and fuming nitric acid
The main controversy between fuming nitric acid and target-based nitric acid is that fuming nitric acid typically produces a colorless, straw yellow, or yellowish brown smoke, while target nitric acid typically produces no smoke; but very high concentrations of this acid can produce whitish smoke.
Will the nitric acid in the wash water interfere with the weight of the silver chloride ?( Nitric acid is prepared by dissolving the gas n2o5 in water
A plate produced by sugar saltpeter will not prevent you from finding a mass of silver ingot in the alloy. … When NaCl is added, old silver ions combine with chloride ions to form a precipitate of AgCl(s), which is filtered off but washed.
Which acid is weaker than benzoic acid p nitrobenzoic acid p methylbenzoic acid p chlorobenzoic acid chlorobenzoic acid
Answer: Will acetic acid be weaker than benzoic acid because the human-bound methyl group in acetic acid gives COO electron density? which is still currently destabilizing the anion. So the correct option is C.

How do you test gold with nitric acid
Acid Nitrate Test Gold is noble opera, which means it resists oxidation and acidity, which is often very difficult. To pass this test, rub any black stone with gold to leave a clear mark. Then apply nitric acid to make marking easier. The acid simply dissolves the base metals, which are not really gold.
