Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore. Allow four hours for the gold to dissolve, stirring every 20 minutes. The chlorine reacts with the gold inside the ore to form gold chloride.

What does hydrochloric acid do to gold
Gold steadily helps even strong acids, the perfect combination of nitric and hydrochloric acids can dissolve it. This combination is specifically known as “aqua regia” which is Latin for “royal water” due to its special ability to burn gold.
Will hydrogen peroxide and hydrochloric acid dissolve gold
Indeed, in the presence of a strong oxidizing agent and its halide anion, gold stainless steel dissolves in strongly acidic solutions. Also, as mentioned, hot hydrochloric acid mixed with hydrogen peroxide (H^sub 2^O^sub 2^) also dissolves the gold, making the reaction too chemical (see Reaction 5).
Can you refine gold with hydrochloric acid
But before we tell you why, let’s explain a little in terms of precious metal dissolution. As a rule, it is not possible to dissolve gold, silver or gold in chemicals based on hydrochloric acid. It is impossible to melt them in acidic nitric acid.
Which of the following is a diprotic acid * hydrochloric acid Sulphuric acid phosphoric acid nitric acid
That’s right, you see, option d) sulfuric acid. (a) Acid: phosphoric acid Phosphoric acid is a triprotic acid.

Why is hydrochloric acid HCl classified as a strong acid while hydrofluoric acid HF is classified as a weak acid
Fluorine is electronegative, so the bond in HF is actually a polar covalent bond. The longer the polar bond, the more convenient it is to remove most of the proton or hydrogen from the acid. Thus, hydrochloric acid (HCl) is much more acidic than acidic hydrogen bromide (HBr). Based on its polarity alone, one would expect HF to be stronger than HCl.
Which of the following does not form an acidic salt is phosphoric acid is carbonic acid is hydrochloric acid IV Sulphuric acid
Weak acids do not produce citrus salts. This acid can be classified as a strong or weak chemical. Sulfuric acid: strong acid. Therefore, phosphoric and carbonic acids do not form acid salts online, as they are likely to be slightly acidic in nature.
Which acid is weaker than benzoic acid p nitrobenzoic acid p methylbenzoic acid p chlorobenzoic acid chlorobenzoic acid
Answer: A solution of acetic acid is weaker than benzoic acid because this bonded methyl group in acetic acid gives the electron density to COO? which further destabilizes the anion. So Fix C.
Can hydrochloric acid and sulfuric acid dissolve gold
As far as I know, gold cannot be contained in dissolved stomach acid; but it must be combined in dissolved form with things other than aqua regia, including cyanide, citrates, and sulfites. On the. … According to the patent, the chemical persulfuric acid P is formed at the anode of each surface, which temporarily dissolves the particular gold.
Why is hydrochloric acid used instead of sulfuric acid in the preparation of boric acid
Boric acid content occurs naturally in volcanic steam jets. … Boric acid is obtained by treating borax with nitric acid, and nitric acid is preferred over hydrochloric acid because sodium nitrate is certainly more soluble than sea salt chloride, and sulfuric acid is difficult to use for laundry, which is so necessary.
Which of the following is Tetrabasic acid a orthophosphoric acid hypophosphorous acid Metaphosphoric acid pyrophosphoric acid
(pyrophosphoric acid) is a tetrabasic agent because it contains 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) Sugar acid. Explanation: Glucose is simply oxidized by nitric acid to form sugar acid.
