Answer is explained in the explanation section below.
Explanation:
Solution:
Note: This question is incomplete and lacks very important data to solve this question. But I have found the similar question which shows the profiles about which question discusses. Using the data from that question, I have solved the question.
a) We need to find the major species from A to F.
Major Species at A:
1. ![Na_{2} CO_{3}](https://tex.z-dn.net/?f=Na_%7B2%7D%20CO_%7B3%7D)
Major Species at B:
1. ![Na_{2} CO_{3}](https://tex.z-dn.net/?f=Na_%7B2%7D%20CO_%7B3%7D)
2. ![NaHCO_{3}](https://tex.z-dn.net/?f=NaHCO_%7B3%7D)
Major Species at C:
1. ![NaHCO_{3}](https://tex.z-dn.net/?f=NaHCO_%7B3%7D)
Major Species at D:
1. ![NaHCO_{3}](https://tex.z-dn.net/?f=NaHCO_%7B3%7D)
2. ![H_{2}CO_{3}](https://tex.z-dn.net/?f=H_%7B2%7DCO_%7B3%7D)
Major Species at E:
1. ![H_{2}CO_{3}](https://tex.z-dn.net/?f=H_%7B2%7DCO_%7B3%7D)
Major Species at F:
1. ![H_{2}CO_{3}](https://tex.z-dn.net/?f=H_%7B2%7DCO_%7B3%7D)
b) pH calculation:
At Halfway point B:
pH = pK
+ log[![CO_{3}](https://tex.z-dn.net/?f=CO_%7B3%7D)
]/[H![CO_{3}](https://tex.z-dn.net/?f=CO_%7B3%7D)
]
pH = pK
= 6.35
Similarly, at halfway point D.
At point D,
pH = pK
+ log [H![CO_{3}](https://tex.z-dn.net/?f=CO_%7B3%7D)
]/[H2
]
pH = pK
= 10.33
(80+125+45) / 10 = 250/10 =25
25 meters per minute= 0.41 meters/second
the direction and stopping time is irrelevant to the problem.

<h3>Monoatomic vs Polyatomic Ions</h3>
In chemistry, monoatomic ions are ions that consist of only a single type of atom. They are usually positive or negatively charged and are otherwise known as simple ions. Examples include
,
, and ![Fe^{3+](https://tex.z-dn.net/?f=Fe%5E%7B3%2B)
Polyatomic ions, on the other hand, are ions that consist of more than one atom, unlike monoatomic ions. The two or more atoms are covalently bonded and the entire structure behaves like a single chemical entity in reactions. Polyatomic ions are otherwise known as molecular ions.
Examples of polyatomic ions are
,
,
,
,
, and ![OH^-](https://tex.z-dn.net/?f=OH%5E-)
Thus, from the diagram:
- Polyatomic ions:
,
,
,
,
, and ![OH^-](https://tex.z-dn.net/?f=OH%5E-)
