If the sample dissolves very quickly, or the solution turns dark brown or yellow, it is likely a base metal. Experience and experimentation can lead to more precise interpretations, but for bullion purposes, silver testing solution is best used as a pass/fail test.
If you are testing with silver acid, the acid will turn deep red for silver not as deep for lower grade and yellow brown for base metal. The acid reacts within seconds to the metals so you shouldn’t be waiting more than twenty or thirty seconds to know the answer. After testing.

What color does silver turn with acid test
When a product has a silver content between 77 and 90%, it turns gray.
What color is silver in nitric acid
During this time, nitric acid can recover from an oxidation state of +5 to an oxidation state of +4 (nitrogen dioxide). During the reaction of Ag and HNO 3 it can be observed that nitrogen dioxide gas gives off a brown color. Silver is a soft, white and lustrous transition metal. The silver-based aqueous nitrate program is colorless.
Can You acid test for silver
Confuses the “acid test” for the yellow metal and other precious metals. Testing silver with a gold assay solution or nitrate, sterling or uncontaminated silver turns slightly milky white as shown, and a few test chemicals for gold over 14 carats can usually overcome the barrier between a particular silver plate and any base metal toy .
Which acid is weaker than benzoic acid p nitrobenzoic acid p methylbenzoic acid p chlorobenzoic acid chlorobenzoic acid
Answer: Acetic acid is less strong than benzoic acid because the elliptical methyl bonded to acetic acid donates an electron to COO. which further destabilizes the anion. So the correct options are C.

Which of the following is Tetrabasic acid a orthophosphoric acid hypophosphorous acid Metaphosphoric acid pyrophosphoric acid
(pyrophosphoric acid) is an ideal tetrabasic acid because it provides four H+ ions.
When glucose is heated with nitric acid the product is a lactic acid B saccharic acid C Glycollic acid D oxalic acid
Answer: 2) Urate sugar crystals. Explanation: Glucose is oxidized by Option Nitrogen to form the sugar chemical.
Which of the following is a diprotic acid * hydrochloric acid Sulphuric acid phosphoric acid nitric acid
Option d) sulfuric acid is correct. (a) Phosphoric acid: The acidity of phosphorus is a triprotic acid.
Is it true that silver chloride turns grey to form silver metal
The color of silver chloride changes from white to gray when the jewelry chloride decomposes, resulting in a gray elemental precious metal. Therefore, the correct response tactic is (A). Note. Like silver chloride, yellow metal bromide undergoes the same decomposition reaction as the metals silver and bromine.
