Mercuric chloride is a soluble salt of Mercury. The mercuric ions in solution interferes with vital enzymes in the cell membrane and cytoplasm of microbes. Unfortunately it is also poisonous to mammalian cells including human cells. It has largely been replaced by safer disinfectants.
alcohol denatures protein and bacteria are made from protein so the bacteria dies.
Mercuric chloride is useful because it separates the proteins of bacteria

The internet is full of useful ways on how to make ammonium chloride. Hydrochloric acid, and ammonia can be combined to produce a chemical reaction which creates ammonium chloride.
Rubbing alcohol is a very useful first aid product. It can be used for many different things. The shelf life of an open bottle of rubbing alcohol is usually a year, but check the use by date.
Sodium Chloride (common table salt) is a very useful compound that is formed by the reaction of two very dangerous and highly reactive elements (namely Sodium and Chlorine).
The most basic / simplest is Methanol Useful alternative #1 is Ethylene Glycol Useful alternative #2 is Propylene Glycol There are also non-glycol, "Organic Acid Technology" (OAT) antifreezes used in some automotive applications.
Alcohol is useful to cleanse things. Alcohol can kill bacteria. Therefore it is often used in a disinfectant. Most of the time it's 70% alcohol 30% water
Normal solution of ferric chloride is acidic in nature and phenol is also acidic so neutral ferric chloride is more useful.
As an anesthetic and disinfectant? When was "back then?"

The bacteria yeast converts sugar into alcohol.
It is not useful at all for that. I use a proprietary brake cleaner from the auto store .
Obviously, sodium chloride is the salt we put onn our food and with out the compound (sodium chloride) we would not have seasoning on our food. Its a major ingredient in edible salt and is commonly used that is why its the most important compound out all others.
Yes, this method is useful.
Sodium chloride is very useful. Sodium ion is the positive ion.
Examples: potassium chloride, ammonium and sodium phosphates, ammonium sulfates etc.
