Not recomended, it would take to much since vinegar is a lot weaker as acids go (hence humans can safely consume it) and there is other organic related compounds that are not good for the pool.
Muriatic acid is just another name for hydrochloric acid.
Acetic acid (vinegar) technically could, but you'd need a HUGE amount of it, as vinegar is not an especially strong acid. Muriatic acid or Sodium bisulphate would do a better job.
pool acid is made up of muriatic or hydrochloric acid that is it.
You can't! Muriatic acid (~32% HCL) will not add any free chlorine to the pool and will not function as a oxidizer (Shock).
liquid pool acid is Muriatic acid or more commonly know as Hydrochloric acid (HCl)
Yes, you can use muriatic acid to control pH in a pebbletec pool. Added correctly (spread around the pool with circulation equipment operating) muriatic acid will not harm the pool. As a matter of fact muriatic or hydrachloric is the best thing to use but I suggest you dilute it 4 parts water 1 part acid for safety to you and your equipment
Hardware stores, Pool shops.

Add potash. See your pool shop with a sample of your water and the size of your pool and he will give you what your pool requires.
