We all know that Biology can be tough sometimes but you have to think of it as this way, as a biology teacher I think that all learners should try my method.
The following answers your question. If you make the pH 5 then it ill be too low for the alkali or acid to reveal its colour but if you put it at 9 it is too high.
So to be safe the pH always needs to be 6-8.

Is a pH of 8 more basic or less than a pH of 6?
The higher the pH, the more basic, so a pH of 8 is more basic than a pH of 6.
What is the pH of cough syrup?
Roughly about 8
What is the difference between a pH of 6 and a pH of 8 in H plus concentration terms?
The difference between a pH of 7 and a pH of 8 are as follows:A pH of 7 means the concentration of [H+] is 10-7.A pH of 8 means the concentration of [H+] is 10-8.Therefore, a substance with a pH of 8 has 1/10th the concentration of hydrogen ions that a substance with a pH of 7.
What do cells rely on to maintain a constant pH in their environment?
By drinking a lots of water and sleeping on the right time(8 hours minimum),Water is PH 7(neutral)so then it can maintain your cells.
What is the pH number of a chemical with a neutral pH?
0-6 on the pH scale are acidic substances. 7 is NEUTRAL - the pH of pure water is 7. 8-14 is basic/alkaline. When discussing drinking water supplies, a pH between 6 and 8 is generally referred to as neutral, because for practical purposes (drinking, cooking, washing etc) they differ very little from pure water. However, technically a pH between 6-7 is still acidic, and 7-8 still alkaline.
Is a pH of 8 more basic or less than a pH of 6?
The higher the pH, the more basic, so a pH of 8 is more basic than a pH of 6.
What will happen to the pH fo a substance if the concentration of hydrogen ions increases from 1.0x10-8 to 1.0x106-6?
- log(1.0 X 10 -8 M)= 8 pH------------ log(1.0 X 10 -6 M)= 6 pH---------The pH lowered in solution 100 times in concentration of H +. From basic, 8 pH, to acidic, 6 pH.
A solution with a pH of 8 has how many times fewer hydrogen ions than a solution with a pH of 6?
pH 8: [H+] = 10^-8 M pH 6: [H+] = 10^-6 M 10^-6 / 10^-8 = 10^2 = 100 Answer is 100 times fewer
What is the pH of cough syrup?
Roughly about 8
In general life needs to maintain a pH level between?
5-8
What is the pH of sodium sulphate?
the pH of sodium sulphate is 6 - 8
What has a pH range from 6-8?
Water
How are pH acids and bases different?
If it is an acid, the pH is 6 and lower. If it is a base, the pH is 8 and higher.
What pH does trypsin work at the best?
The optimal pH for trypsin is 8. It is found in the small intestine and digests proteins and polypeptides there.
What is a base on the pH scale?
A base is anywhere from 8 to 14 on the Ph scale. If a base of about 8 is added to and acid of about 6, the Ph will be balanced out.
How many times more acid is a solution with a pH of 4 than a solution of pH of 6?
pH 8: [H+] = 10^-8 M pH 6: [H+] = 10^-6 M 10^-6 / 10^-8 = 10^2 = 100 Answer is 100 times fewer
If pH is 6 What is is OH?
pH + pOH = 14. So pOH = 14 - 6 = 8 pOH = -log[OH-] [OH-] = 10-8 M
