Theoritically, there exists no acid that can fully dissociate into ions in aqueous medium.
Though, for practical purposes, it is often assumed that strong acids such as nitric acid, hydrochloric acid etc. are fully dissociated.
Other than these few strong acids, all other acids partially dissociate, a common example is acetic acid.
An acid that does not dissociate 100 percent into its ions is called a weak acid. Weak acids partially dissociate in water to form H+ ions and their conjugate base. Examples include acetic acid (CH3COOH) and citric acid.
The majority of strong acids ionize 100% in water, meaning they completely dissociate into ions. Examples of strong acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3). On the other hand, weak acids only partially ionize in water, resulting in an equilibrium with both dissociated and undissociated forms present.
The chemist will use 100 liters of the 80% acid solution and 100 liters of the 30% acid solution to make a 200-liter solution that is 62% acid. The amount of acid in the 80% solution will be 0.8 * 100 = 80 liters, and in the 30% solution, it will be 0.3 * 100 = 30 liters.
It will not dissociate 100% in water.
100% sulfuric acid rapidly decomposes until it reaches a concentration of 98%. This concentration is usually referred to as concentrated sulfuric acid. The pH value of 98% sulfuric acid is approximately -1.5 For comparison, sulfuric acid of this concentration has about 300 times as many active hydrogen ions as stomach acid (approximate pH 1).

Because H3BO3 is a weak acid, where H3PO4 is a strong acid. Strong acids dissociate 100%, whereas weak acids do not.

Yes - low pH means a stronger acid because pH is the NEGATIVE logarithm to base 10 of the [H+] ion concentration. Hydrochloric acid is a strong acid in that it fully ionizes and has a higher concentration of hydrogen ions on a like for like basis than ethanoic acid (acetic acid) which is a weak acid in that it does not fully dissociate.
Strong acids/bases will dissociate to almost 100% in water and their conjugate base/acid will be weak. Weak acid/base will not dissociate well in water and their conjugate base/acid will be strong.
Oil of vitriol.
So, ammonium hydroxide is a weak base. Weak base means that it dissociate slightly in water, that is, it does not dissociate 100% in water. This is because, when ammounium hydroxide reacts with water it forms hydrogen ions. But as the reaction is very revesible it will never react completely with water, that is, it will never dissociate completely with water. Thus, it is a weak base.
Weak acids do not completely dissociate in water, meaning they only partially ionize. This results in a lower concentration of hydronium ions compared to a strong acid at the same concentration. Additionally, weak acids have higher pKa values compared to strong acids.
Since HI is considered a strong acid, it will dissociate 100% leading to 0.50 M H+ and 0.50 M I-. So, the answer would be 0.50 M.
