The choice of which indicator to use is determined by the range of pH where the indicatir changes colour and the equivalence point of the neutralisation reaction. Methyl orange changes color between pH3 and 4, phenolphthaein between and 8 and 10. It depends on what you are titrating which one you choose.
Methyl orange is used as an indicator in titrations involving strong acids and strong bases due to its color change at a low pH (red) and high pH (yellow). Phenolphthalein, on the other hand, is more suitable for acid-base titrations involving weak acids and strong bases as it changes color at a higher pH range (colorless to pink).

How do you prepare methyl orange indicator for titration?
To prepare methyl orange indicator for titration, dissolve 0.1g of methyl orange powder in 100mL of distilled water. This will give you a 0.1% solution of methyl orange which is suitable for use as an indicator in acid-base titrations.
Is methyl orange the indicator used in the titration of na2co3 against hcl solution?
No, methyl orange is not commonly used as the indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is the indicator of choice for this titration, as the endpoint is at a pH of around 8.2, which is the color change range of phenolphthalein.
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.
Can you use indicator other than phenolphthalein in the titration of NaOH?
Yes, you can use indicators such as bromothymol blue or methyl orange in the titration of NaOH. These indicators change color at different pH ranges and can be used based on the specific pH endpoint needed for the titration.
Is methylorange the indicator used in the titration of Na2CO3 against HCl solution?
Methyl orange is not commonly used as an indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is a suitable indicator for this titration because it changes color in the pH range of the equivalence point.

How can you determine total acidity?
By titration with alkaline on methyl-red indicator (pH<6)
Is methylorange the indicator used in the titration of Na2CO3 against HCl solution?
Methyl orange is not commonly used as an indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is a suitable indicator for this titration because it changes color in the pH range of the equivalence point.
Which indicator is used in titration of naoh and h2so4?
Phenolphthalein is commonly used as an indicator in the titration of NaOH and H2SO4. It changes color from colorless to pink as the solution reaches a specific pH range, signaling the endpoint of the titration.
Why we used methyl red as indicator in titration borax with HCL?
Methyl red is used as an indicator in the titration of borax with HCl because it changes color in acidic conditions. This allows for the precise determination of the endpoint of the titration, which is when all of the borax has reacted with the acid. The color change indicates the shift from basic to acidic conditions, helping to stop the titration at the correct point.
What is the mechanism of methyl orange in sodium carbonate and hydrogen chloride titration?
In the presence of sodium carbonate (base) and hydrogen chloride (acid) in a titration, methyl orange indicator changes color at the endpoint. At the beginning of the titration, the solution is basic due to the sodium carbonate, causing the methyl orange to appear yellow. As the acid is added and the solution becomes more acidic, the indicator changes to red at the endpoint when all the base has been neutralized by the acid.
Why is thymol blue used as the indicator for titration of acetic acid and naoh?
Thymol blue changes color in the pH range of 8.0 to 9.6, making it suitable for titrations involving acetic acid (pKa ~ 4.75) and sodium hydroxide. At the equivalence point of the titration, the pH is around 8.5, which falls within the indicator's color change range, allowing for a sharp color transition at the endpoint.
What is the color of the end point for the titration of the acid?
The color of the endpoint for the titration of an acid depends on the specific indicator used. Common indicators include phenolphthalein (pink at high pH), methyl orange (red at low pH), and bromothymol blue (yellow at low pH). The choice of indicator will depend on the pH range of the acid being titrated.
Why methyl orange is used as indicator in determination of ZnO?
Methyl orange is used as an indicator in the determination of ZnO because it changes color from red to yellow at a pH range of 3.1-4.4, which is suitable for the titration of ZnO with a strong acid like hydrochloric acid. This color change helps in determining the endpoint of the titration accurately.
