when the ph=7 means it is newtral so the colour is newtral just as water that means colries
*edit* don't answer any more questions please! Methyl Orange is yellow at pH > 4.4, Red at pH <3.1 and the colour change yellow-orange-red happens in the small interval between those two values.
What else can I help you with?
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 a orange pH?
If the PH is orange, it means the substance is acidic :)
Could you use Methyl red to indicate the pH of bleach?
Methyl red is not suitable for measuring the pH of bleach due to the presence of strong oxidizing agents in bleach, which can react with and potentially destroy the dye. Instead, pH indicators that are stable in the presence of strong oxidants, such as phenolphthalein or bromothymol blue, would be more appropriate for indicating the pH of bleach.
What colour is bromothymol blue?
Bromothymol blue is a pH indicator dye that is typically blue in alkaline conditions (pH > 7), green in neutral conditions (pH = 7), and yellow in acidic conditions (pH < 7).
What is the pH of Butanone?
The pH of butanone (also known as methyl ethyl ketone) is neutral, as it does not contain any ionizable hydrogen ions. It is a neutral compound that does not affect the pH of a solution when dissolved in water.
How do you recognize an alkali?
With help of ph indicators like litmus paper and methyl orange. Ph of alkali is above 7, below 14
What are the Absorption spectrum of methylene blue and methyl orange?
The absorption spectrum of methylene blue shows peaks around 600-660 nm due to its blue color. Methyl orange, on the other hand, shows peaks around 425-465 nm, which corresponds to its orange color. These peaks indicate the wavelengths at which these dyes absorb light most efficiently.

Solutions having pH lower than 7 are?
a Ph lower than 7 is an acid x that is orange/red the darker the colour the more acidic otherwise Ph 7 is neutral and over 7 is an alkali which goes blue/purple the darker the colour the more alkali x
What happens when hydrochloride in dry form is dissolved in methyl benzene?
pH less than 7
What number of pH is in pure water?
pH 7 and the colour green it is neutral.
What is a orange pH?
If the PH is orange, it means the substance is acidic :)

Why you use two indicator?
Because the end-pointsof these titrationshave different pH values. A strong acid / strong base titration has an endpoint of pH 7, and an indicator that changes near 7 is useful. Phenolphthalein changes around pH 8.5 which is close enough for government work (so to speak).A strong acid - weak base titration will have an endpoint below 7, and so an indicator that changes over a range that is less than 7 should be used. Methyl orange changes around pH 4.
