    Hello, dear friend and teacher
    I had a question. I had some stones that I crushed and powdered
    After washing it, I put a little sulfuric acid and nitric acid on it. After a few hours, I took the stannous chloride test solution and it turned black, but after this step, after I washed it and applied acorgia acid, the stannous chloride test gave the correct answer.

    • @Goldchannel
      @Goldchannel  6 місяців тому +1

      Hello sir ;
      It sounds like you're performing a series of chemical tests to identify the presence of certain metals, possibly gold, in your crushed and powdered stones. Let's break down the steps and the likely reactions involved.
      • Crushing and Washing: You crushed the stones and washed them, likely to remove any loose dirt or other impurities.
      • Acid Treatment:
      • Sulfuric Acid (H₂SO₄): This strong acid could be used to dissolve basic oxides and some other impurities.
      • Nitric Acid (HNO₃): This strong oxidizing acid could be used to dissolve metals and other impurities, potentially forming nitrates.
      • Stannous Chloride Test:
      • Initial Black Color: When you added stannous chloride (SnCl₂) after the acid treatment, the solution turned black. This could indicate the presence of a noble metal such as gold or platinum. Stannous chloride is commonly used to detect gold because it reduces gold ions (Au³⁺) to colloidal gold, which appears black.
      • Ascorbic Acid Treatment:
      • Ascorbic acid (vitamin C) is a reducing agent. It can reduce metal ions to their elemental state or to lower oxidation states. For example, it can reduce gold ions (Au³⁺) to metallic gold (Au⁰).
      • After treating with ascorbic acid, any remaining metal ions that could interfere with the stannous chloride test would be reduced.
      • Correct Stannous Chloride Test After Ascorbic Acid:
      • After washing and applying ascorbic acid, the stannous chloride test gave the correct answer, indicating a positive result for the presence of the targeted metal, likely gold.
      • The black color did not reappear, suggesting that the ascorbic acid successfully reduced interfering metal ions, allowing the stannous chloride to specifically indicate the presence of gold.
      Explanation of Steps:
      • Initial Acid Treatment: This step is crucial for breaking down the sample and dissolving metals into solution.
      • Stannous Chloride Test: Initially, it might have given a false positive due to other interfering substances or an excess of metal ions.
      • Ascorbic Acid: It clears up these interferences by reducing metal ions, ensuring that the stannous chloride test gives a more specific and accurate result.
      Conclusion:
      The initial black color in the stannous chloride test indicates the presence of metals, potentially gold. The use of ascorbic acid then helps clarify the results by removing interferences, confirming the presence of the metal. This process is common in qualitative analysis to detect and confirm specific metals in a sample.

      @@Goldchannel Hello dear professor
      After I crushed and washed the stone, the next step was to combine nitric acid with sulfuric acid and pour it on it. After a few hours, I took a stannous chloride test, which was positive. At this stage, shouldn't the stannous chloride test be negative, and after that again? I washed it and applied nitric and hydrochloric acid to it, will the test be positive after this?

      There are several ways to extract gold without using nitric acid.

    • @Goldchannel
      @Goldchannel  4 роки тому

      The method is analogous to that used for the analysis of gold (and silver) in the cupellation process when these two metals are separated by inquartation, and consists of dissolving the silver with an acid without attacking gold, but in industrial refining sulfuric acid is used instead of nitric .
      remove the base metals, it is attacked with boiling sulfuric acid which dissolves the silver, which will subsequently be precipitated in the form of chloride, gold remaining unattacked. The operation will be successful if it remains in the tank in the form of a sponge and does not disintegrate into fine particles which would be entrained: it depends on the composition of the metal to be refined.

      لانه هذه النوع من الحجارة تحتوي على أكسيد الحديد الثلاثي مركب كيميائي له الصيغة Fe2O3، ويكون على شكل مسحوق بلوري بني محمر. وهو المكون الأساسي للصدأ. ف حمض الكلوردريك يزيله بعد غسله به أو غليه
