Methyl orange is not suitable for acid-base titrations because its color change occurs over a broad pH range (pH 3.1 to 4.4), making it less precise for determining the endpoint of the titration. It is also susceptible to interference from other substances present in the solution, leading to inaccurate results. Other indicators, such as phenolphthalein or bromothymol blue, are preferred for acid-base titrations due to their sharper color changes at specific pH values.

What is the similarities between both methyl orange and screen methyl orange?
Methyl orange and screened methyl orange are both synthetic dyes commonly used as indicators in titrations. They both change color at specific pH ranges: methyl orange transitions from red to yellow in acidic solutions, while screened methyl orange transitions from yellow to red in basic solutions. Both dyes are water-soluble and widely available for laboratory use.
Why methyl orange used in the titration and not other indicator?
Methyl orange is commonly used in acid-base titrations because it changes color sharply in the pH range of about 3.1 to 4.4, making it easy to detect the endpoint. Other indicators may have different color change ranges that may not be ideal for acid-base titrations.
What is the equation of titration with methyl orange?
The equation of the titration using methyl orange as an indicator depends on the specific reaction being titrated. Methyl orange is typically used in acid-base titrations, where the indicator changes color in the presence of a certain pH range. For example, in a titration of a strong acid (e.g., HCl) with a strong base (e.g., NaOH), the equation would involve the stoichiometry of the acid-base reaction, with the color change of methyl orange indicating the endpoint of the titration.
Why methyl orange is used instead of phenolphthalein in hcl and naoh titration?
This is so since the pH at the end point of Phenolphthalein is 9.1 and methyl orange is 3.7. For a strong acid strong base titration which the end point is between 3-11 phenolphthalein is used
Why methyl orange used in the titration?
Methyl Orange is used as an indicator in a titration.It helps us to know the end point of a titration and when do we stop adding the acid or the base. It is yellow in bases,orange in neutral compounds(thats the colour of methyl orange at the end point) and red in an acidic medium.
What is methly orange?
Methyl orange is a pH indicator frequently used in titrations. It is often chosen to be used in titrations because of its clear colour change. Because it changes colour at the pH of a mid-strength acid, it is usually used in titrations for acids. Unlike a universal indicator, methyl orange does not have a full spectrum of colour change, but has a sharper end point. Check out the Related Link for more details.

Examples of primary standards used in acidbase titrations?
Oxalic acid,sodium oxalate or ammonium iron (II) sulfate.

What are some other ways that acid base titrations are used?
Acid-base titrations are usually conducted with an indicator. Indicators are used to measure the end point precisely. Some of common indicators are methyl red, methyl orange and bromothymol blue.
Why phenolpthalein use first before methyl orange?
Phenolphthalein is typically used first in acid-base titrations because it has a clear color change from colorless to pink around a pH of 8.2 to 10, making it ideal for detecting the endpoint of strong acid versus strong base titrations. Methyl orange, on the other hand, changes color from red to yellow between pH 3.1 and 4.4, which is better suited for strong acid versus weak base titrations. Using phenolphthalein first allows for a more precise determination of the endpoint in higher pH ranges before transitioning to methyl orange for lower pH applications.
What is methyl orange and where it is used?
Methyl orange is a pH indicator having the chemical formula C14H14N3NaO3S.
What are two different types of indicators used in acid base titration?
Two common types of indicators used in acid-base titrations are phenolphthalein and methyl orange. Phenolphthalein changes from colorless to pink as the pH transitions from acidic to slightly basic, making it suitable for strong acid-strong base titrations. Methyl orange, on the other hand, shifts from red to yellow in the pH range of 3.1 to 4.4, making it ideal for titrations involving strong acids and weak bases. Each indicator is chosen based on the pH range of the equivalence point of the specific titration being conducted.
Functional group in methyl orange?
Methyl orange is red under a pH=3,1 and yellow over a pH=4,4; methyl orange is useful for the titrimetric determination of acids concentration.
