What will sulfuric acid do to silver
When silver reacts with dilute sulfuric acid, it cannot decompose hydrogen. This makes the reaction impossible. It’s the same with concentrated sulfuric acid, but if you let the silver react with hot, strong sulfuric acid, you get yellow metal sulfate.

Does silver dissolve in sulfuric acid
Since silver is a relatively inert metal, it cannot be dissolved in hydrochloric or sulfuric acid.
Can you refine silver without nitric acid
If you want to spruce up the silverware in your home with an acid-based material, you can easily do so. Baking soda is one of the most commonly used products to restore shine and cleanliness. Clean your silverware without harsh acid exposure.
Can you test silver with sulfuric acid
A. The easiest way to test silver accessories is to scrape the item on a rough, flat stone, add sulfuric acid, and then rinse with salt water. If it programs pure white, then its color is 100% pure. It’s off-white and then it goes from 85 to 60 percent mph.
Which acid is weaker than benzoic acid p nitrobenzoic acid p methylbenzoic acid p chlorobenzoic acid chlorobenzoic acid
Answer: Acetic acid is a weaker acid solution than benzoic acid because the basic methyl group bound in acetic acid imparts the electron density COO? which further destabilizes the anion. So the correct choice was C.
Why is a strong acid such as sulfuric acid used in a Fischer esterification reaction when there is already a carboxylic acid present
Sulfuric acid is a hydronium that protonates carbonyl-type oxygen ions, making the new carbonyl carbon a better electrophile.
Which is a stronger acid sulfurous acid or sulfuric acid Why
The main difference between sulfuric acid and sulfurous acid is the oxidation state of sulfur. Also, when comparing the two chemicals in terms of acidity, acidic sulfuric acid is more acidic than the sulfurous response. In other words, sulfuric acid was a very strong acid and sulfuric acid was relatively weak.
Why is hydrochloric acid used instead of sulfuric acid in the preparation of boric acid
Boric acid occurs naturally volcanically with steam jets. … Boric acid is made by treating borax with nitric acid, and nitric acid is often chosen over hydrochloric acid because, unlike sodium chloride, brine nitrate is more soluble and sulfuric acid is difficult to wash off, so it is not used.
Which of the following is Tetrabasic acid a orthophosphoric acid hypophosphorous acid Metaphosphoric acid pyrophosphoric acid
(pyrophosphoric acid) is a tetrabasic acid because it provides four H+ ions.
