Now, i might be wrong but, you have to make a hypotosis of possible theories as to what the truck is doing. Then observe what changes were made after the salt was added then the question should be why was the salt added and how it changed the area. I hope this helps!
Glycine is the simplest amino acid there is. Its structural formula is shown in the attached picture. Amino acids are characterized with having an amine group and a carboxylic group at both ends of the terminals. Carboxylic acid is acidic so it has a partial negative charge on one side. Amines are basic so it has a partially positive charge on the other side. Possessing this property of having opposite charges at once is called a zwitterion. That is what is meant by the pKa values. These are the pH values of the individual functional groups. The pKa 2.34 is for the carboxylic group while pKa 9.6 is for the amine group.
These electrostatic attractions depend on the pH of the solution. At pH 12, the functional group that predominates is the carboxylic group with an overall charge of -1 as shown in the second picture.
Answer:
A complex ion contains a central metal ion bound to one or more ligands
Explanation:
A complex ion is consists of a central atom or ion, that is usually metallic, called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.
An example of a complex ion is
[Co(NH3)6]3+
Please go through the attached file for a proper representation of the complex ion.

A metal and nonmetal are bonded together by exchanging electrons. I'm not sure what you mean by "why".
Hope I helped! :)
