Examples of hydrogen sulfide can be found as in sewerage channels.

Hydrogen sulfide is heavier than air that it is more likely to collect and settle in a lower area. This type of compound is also corrosive that it is able to convert certain metals into rusty. In low concentration, this compound will smell like rotten eggs that in the long term it will be able to paralyze the human olfactory senses.

  • Chemical formula: H2S
  • Ionization Reactions: H2S → S2- + 2H+

6. Nitrite Acid

Nitric Acid is a kind of corrosive and colorless liquid. This acid is included in type of toxic acid that can cause burns. As a solution, 86% of the solution content is nitric acid.

The solution as commonly referred to as smoky nitric acid can also be subdivided into two types of acid which are white smoky nitric acid and red smoky nitric acid.

Nitric acid solutions are commonly used to produce explosive materials such as nitroglycerin, trinitrotene (TNT) and cyclotrimethylenatrinitramine (RDX).

  • Chemical formula: HNO2
  • Ionization Reactions: HNO2 → N02- + H+

In daily life, ammonium hydroxide is used in household cleaners, alkyl amines, tobacco management, furniture darkening and many others.

In the laboratory, ammonium hydroxide used in traditional qualitative inorganic analyzes used as complexes and bases.

  • Chemical formula: NH4OH
  • Ionization Reactions: NH4OH(aq) → NH4+ (aq) + OH (aq)

10. Anilina

It is also generally referred to as phenylamine or aminobenzene. The content in aniline is an amine group, with aniline characteristics of liquid at room temperature, colorless, volatile and cause unpleasant odors such as rotten fish.

In daily life, aniline is widely used as a dye, raw material of producing various drugs such as antipirina and antifebrin. However, frequent use of aniline can also be harmful as it can cause nausea, vomiting, dizziness and headaches. In addition, some experts also mentioned that excessive use of aniline can also lead to insomnia.

Chemical formula: C6H5NH2

11. Phenol

Phenol or also commonly referred to as carbolic acid is colorless crystalline solid. In daily life phenol is commonly used as a material to sterilize the surgical equipment. In addition phenol is also used in manufacture of drugs, synthetic resins and polymers. However, it is required to be highly careful in using phenol in case of misapplication that it can cause skin irritation.

In nature, many formic acids are produced by insects from the Hymenoptera, such as bees and ants as an attack or defense tool. In addition, formic acid is also the result of significant combustion of alternative fuels, which is combustion of methanol mixed with gasoline.

Chemical formula: HCOOH

List of weak electrolyte examples can generally be formed from weak acids or bases as well. Which means, when acid or weak base is mixed with the solvent, then only part of the solute will ionize the process, while the rest will be molecules.

In daily life, in order to determine whether or not that the solution is included in weak electrolyte, it can be observed in weak electrolyte characteristics of weak electrical conductivity. This can be easily verified by using electronic test device that you can make it yourself by using basic materials of batteries, cables and lamps.

If the solution you were testing turns the lights on but dimmed and the bubbles come up, it means that it is included in weak electrolyte solution. The dimmed lamps and bubbles indicate that electrical conductivity of the solution is fairly weak. And the generated bubbles will seem scarce, as indeed the resulting ion is short.
