Talk:Nile blue

Formula

Shouldn't it look like (C₂₀H₂₀N₃O)₂·SO₄ ?

Yes very likely, those ids were confusing sulfate, chloride, ion and a neutral molecule. Based on IUPAC name the real thing should be a sulfate. We would need a new diagram too. Graeme Bartlett (talk) 00:55, 8 September 2021 (UTC)[reply]

History

Presumably this was named after the blue colour of either the River Nile, or particularly the Blue Nile. If so, please add this and other historical information (with references) to the article. —DIV (1.129.107.248 (talk) 11:35, 26 October 2019 (UTC))[reply]

Table from source 1

The table was correctly copied from the source to the article but according to my chemistry knowledge, the source is wrong.

1N HCl has a pH of 0 (instead of 1 as they wrote) and 0.1 N NaOH has a pH of 13 (not 11).

Or am I wrong? 134.76.3.233 (talk) 17:38, 31 March 2023 (UTC)[reply]
