Chembox image: acid or anion?
The chembox image shows the tetravalent anion. Shouldn't it show the acid instead? I know that biochemists think that the whole world is dissolved in water, but non-bio chemists think that the names of such substances should refer to the anhydrous solid (or, at most, some definite solid hydrate). --Jorge Stolfi (talk) 00:41, 9 March 2019 (UTC)

Byproducts
The synthesis image should show the byproducts too, if not too complicated. What are they (Stoichometrically, they could be two formic acid molecules.) --Jorge Stolfi (talk) 00:47, 9 March 2019 (UTC)
