<h3>What is
Concentration?</h3>
- Concentration means focused attention, and it has many uses and benefits. It assists in studying, enables faster comprehension, improves memory, helps in focusing on a task, job, or goal, and enables you to ignore meaningless and irrelevant thoughts.
- Taking very small breaks by refocusing your attention elsewhere can dramatically improve mental concentration after that. The next time you are working on a project, take a break when you begin to feel stuck. Move around, talk to someone, or even switch to a different type of task.
- Concentration difficulties can be caused by medical, cognitive, or psychological problems or may be related to sleep disorders or medications, Psychological conditions that can interfere with concentration include anxiety, depression, bipolar disorder, emotional trauma, and stress.

No, because you are not changing the chemical make-up of the paper
Answer:
<u> </u><u>85.952 ml</u> needed to titrate the excess complexing reagent .
Explanation:
Lets calculate
After addition of 80 ml of EDTA the solution becomes = 20 + 70 = 90 ml
As the number of moles of =
=
=0.01172
Molarity =
=
=0.000586 moles
Excess of EDTA = concentration of EDTA - concentration of CoSO4
= 0.009005 - 0.000586
= 0.008419 M
As M1V1 ( Excess of EDTA ) = M2V2
V2 =85.952 ml
Therefore , <u>85.952 ml </u> needed to titrate the excess complexing reagent .
