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.
What else can I help you with?
Is a pH of 8 more basic or less than a pH of 6?
Oh, dude, a pH of 8 is definitely more basic than a pH of 6. It's like comparing a chill day at the beach to accidentally eating a spicy pepper. pH scale goes from 0 to 14, so 8 is closer to neutral (7) than 6, which is getting a bit acidic.
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 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.
What is the color of phenolphthalein in solutions with pH values ranging from 2 to 6?
Phenolphthalein is colorless in acidic solutions with a pH below 8, and turns pink in basic solutions with a pH above 8. In solutions with pH values ranging from 2 to 6, phenolphthalein would remain colorless.
What is the number related to a pink basic solution if seven is normal pH?
basic pH>7, normally 8 to 14neutral pH=7acid pH
Which indicator is used for 8-6 pH?
Bromothymol blue (pH 6.0-7.6) Phenol red (pH 6.4-8.0) Neutral red (pH 6.8-8.0)
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 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.
In general life needs to maintain a pH level between?
5-8
What has a pH range from 6-8?
Water
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.
Is a pH of 8 more basic or less than a pH of 6?
Oh, dude, a pH of 8 is definitely more basic than a pH of 6. It's like comparing a chill day at the beach to accidentally eating a spicy pepper. pH scale goes from 0 to 14, so 8 is closer to neutral (7) than 6, which is getting a bit acidic.
If pH is 6 What is is OH?
pH + pOH = 14. So pOH = 14 - 6 = 8 pOH = -log[OH-] [OH-] = 10-8 M
What is the pH of Maalox?
Maalox has a pH range of about 6 to 9, depending on the specific formulation.
Two solutions A and B have a pH of 6 and 8 what is their nature?
Solution A is weekly acid Solution B is weekly basic
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
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.
