What is range of methyl orange?
The pH range of methyl orange is typically between 3.1 (red) and 4.4 (yellow).
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.
Is methyl red pink at pH9?
it is red in pH under 4.4, yellow in pH over 6.2, and orange in between. Basically color of methyl red at pH 6 is ORANGE.
How does time affect the pH of orange juice?
Over time, the pH of orange juice can decrease due to the natural oxidation of the juice, which can lead to an increase in acidity. The longer the orange juice is exposed to air, the greater the chance of pH changes occurring. It's recommended to consume orange juice soon after it's been freshly squeezed to maintain its pH level.
What is the pH range for carbonate bicarbonate buffer?
The pH range for carbonate-bicarbonate buffer is 9,2.
Why is phenophthalein called an indicator?
Because phenophthalein has the specific ability. Phenophathalein can convert color from colorless(at pH < 8 approximately) into pink (at pH >,= 8 approximately). With this ability, it can indicate properties of other substances which is change in pH.

What is the Ph range of xylenol orange indicator?
These are two indicators:Methyl orange: pH of 3.1 (color red) to 4.4 (color yellow)Phenolphtalein: pH of 8.2 (colorless) to 10.0 (color purple)1 and 2 toghether: pH of 3.1 red to 4.4 yellow, staying yellow up till 8.2,then changing to greenish-purple from 8.2 at 10.0

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.
Why there is no colour change when phenolphthalein is added to the oxalic acid?
Oxalic acid is a weak acid and phenolphthalein is a pH indicator that changes color in the pH range of 8.2 to 10. Oxalic acid solutions typically have a pH below the range where phenolphthalein changes color, so there is no visible change when phenolphthalein is added to oxalic acid.
What is the colour of orange juice on PH paper?
Orange juice is acidic due to its citric acid content, which typically results in a pH below 7. When tested with pH paper, which changes color based on the acidity or alkalinity of a substance, orange juice would likely turn the pH paper to a color indicating acidity, such as red or orange. The exact color would depend on the pH range of the particular pH paper being used.
What is the pH level of orange?
The pH level of an orange is 4.3.
What is the colour of methyl orange when acidic?
Methyl orange changes colors while in the middle of the acidic range so it is only used as an indicator to determine just how acidic a solution is. Below a pH of 3.1 it is red. As pH gets higher it goes to an orange color until it gets above a pH of 4.4 where it will be yellow.
What is pH level of orange juice?
The pH level of Orange Juice is 3.3
