I don't know ... I have the same problem . I found this in a chemestry problem , and my teacher couldn't tell me the answer . He told me to search for it, but I can't find anything about the reaction between Methyl Orange and HCl .. If you could help me , please leave a message at YM : valentin_gr2008@Yahoo.com
Thanks !

Which indicator is used in titration of naoh and h2so4?
Methyl orange
Can you use indicator other than phenolphthalein in the titration of NaOH?
Yes you can use methyl red, methyl orange, bromophenol blue and other indicators instead of phenolphthalein in the acid-base titration of NaOH.
Why is thymol blue used as the indicator for titration of acetic acid and naoh?
An indicator that changes its colour around pH value 5 should be used in this titration. Alternatively, instead of Thymol Blue, Methyl Orange or Methyl Red may be used.
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
What indicator can you choose for the titration of oxalic acid with sodium hydroxide?
Phenolphthalein, because NaOH is a strong base.

What is the solution of NaOH in methyl orange indicator?
Methyl orange shows yellow color in an NaOH solution.
Why is thymol blue used as the indicator for titration of acetic acid and naoh?
An indicator that changes its colour around pH value 5 should be used in this titration. Alternatively, instead of Thymol Blue, Methyl Orange or Methyl Red may be used.

In HCl and NaOH titration which indicator is used?
Phenolphthalein indicates red for acids and blue for bases.
Which indicator is used for titration of C2H2O4 with NaOH?
Phenolphtalein change colorless at pH < 8 to purple blue at pH > 8 to 10
What is the colour change in the titration of NaOH and C2H2O4 if using phenolphthalein as an indicator?
Adding NaOH-sol'n to oxalic acid, C2H2O4, the colour (from colorless) has to become purple-blue at pH 8 to 10.
What happened if some solution splashes out during the titration of NaOH?
If some solution splashes out during the titration of NaOH, the volume at the end point will be wrong.
Why is it necessary to standardize the NaOH solution before titration?
It allows the concentration of the NaOH to be known.
