[edit] wikify

if someone cares to take the trouble, this article needs to reformatted to conform to the other chemical-related articles. Shaggorama 23:13, 11 April 2006 (UTC)

[edit] Inconsistency?

The text says that the modified methyl orange's colours are grey and green, but the diagram shows colourless (?) and purple...? 86.148.60.205 20:14, 2 March 2007 (UTC)

When I used it recently for some chemistry coursework, the colours of screened methyl orange were (alkali)green to purple(acid). If someone could find a source that verifies this it could be fixed. Stealth Wilde (talk) 19:40, 1 April 2008 (UTC)

[edit] Incorectness!

That isn't the correct structure of methyl orange there! When it acts as a base, the H+ does not add itself onto the O- in the SO3 group, but instead into one of the 'middle' N's, causing a shuffle-round of elecrons converting the non-sulphate arene into a cyclohexdiene group and placing a + charge on the 'outmost' N. —The preceding unsigned comment was added by Luke1001 (talk • contribs) 18:31, 18 March 2007 (UTC).

[edit] neutral

what colour is Methyl orange in an neutral solution? --I.W 20:59, 26 March 2007 (UTC)

 -- Yellow, as pH 7 is out of the range of its changes and so is in its closest colour, which is 4.4, being yellow.--82.0.164.177 17:32, 15 October 2007 (UTC)

[edit] Synthesis

I tried to find a decent page on the synthesis of this stuff, but came up empty. I think some information on the synthesis of methyl orange would be helpful as it is a common thing made in organic chemistry lab
