Talk:Chromate

From Wikipedia, the free encyclopedia

Dichromate isn't a salt, it's an ion.

See the salt article. Anions are often named with respect to their conjugate acids, so e.g., dichromate is the salt of chromic acid, and nitrate is the salt of nitric acid. --Diberri | Talk 03:27, Sep 15, 2004 (UTC)

If sodium chromate is so common why is there no pecific page about it?

[edit] Question about H₃O⁺

2 CrO₄²⁻ + 2 H₃O⁺ → Cr₂O₇²⁻ + 3 H₂O

Note: Someone please check above for accuracy, H₃O⁺, should it not be H₂O if it's in an aqueous solution, if this is not true, please send me a reason why, to psychicpanda@gmail.com, thanks, otherwise fix the error. Or is this because to be balanced on one side it requires 2 H₃O⁺ to balance the ^2-, though I thought that in water, it does not need to be balanced, unless as stated above its in equilibrium, which means that it doesn't need to be ionically balanced, but balanced on both sides, as in the anions and cations are equal on both sides, but not adding up to a neutral charge.

The reaction is correct. H₃O⁺ can exist in solution; it's a hydrated H⁺ ion, which you could get by dissolving an acid. See: Acid#Chemical characteristics. Hashproduct 01:30, 2 May 2007 (UTC)

[edit] Separate and improve?

I suggest separating chromate and dichromate into two articles. They also both need a polish and more information. Bob782 (talk) 13:50, 6 February 2008 (UTC)
