Question

In my book it's written that silver nitrate and hydrogen peroxide are kept in brown bottles because they would decompose in the presence of light. Then what is their use and how do we use it in the open

Solution

Hydrogen peroxide decomposes back to water and oxygen when exposed to air and light. When bought at a pharmacy for home use, hydrogen peroxide is sold in dark bottles that are labeled as a concentration of 3% by weight. A chemistry student wants to test the concentration of hydrogen peroxide that has been decanted to light and dark bottles, and exposed to air for 10, 20 and 30 hours. The concentration is tested by titration with potassium permanganate, and each sample is tested twice. The uses are
  • Disinfect Small Wounds. Hydrogen peroxide is a natural anti-septic, therefore one of its most common uses is to clean wounds to prevent infection.

now silver nitrate—— it also wont deforms for some hours , uses are

Test for the presence of Chlorine, Bromine and Iodine ions.
For example: White=Chloride, Pale Yellow=Bromide, Yellow=Iodide.
Test for the presence of Carbonate, Hydroxide, Sulfide and Phosphate ions.
For example: Pale Green=Carbonate, Brown=Hydroxide, Black=Sulfide.
Silver Nitrate is used to test the exact salinity of Sea Water. (it’s about 35 grams per Liter, by the way…)
Silver Nitrate is used in Oil Fields to determine the amount of Chloride ions in water and drilling fluids.

In Manufacturing

Silver Plating – electroplating Silver onto a base metal such as Nickel.
Mirrors – you can Google “Tollen’s Reagent” to learn all about this process.
Hair Dye.
Inks, like indelible, permanent fabric marker pens.
Explosives, like Silver Fulminate, Silver Azide and Silver Acetylide.
Pharmaceuticals.
It prevents premature shrinking or dropping of buds and blooms, in cut flowers. (2.83% solution)
It inhibits cut flowers from making ethylene, which causes them to ripen.
