Hi. Days ago i made sodium molybdate from sodium hydroxide and molybdenum trioxide, I'm sure both reagents are very pure. Accidentally i added little
bit more hydroxide next i added small amount of HCl and make white molybdate powder i dissolved it in water and i saw this red powder. Any ideas about
what it's?

Vano, when you added your NaOH to our MoO3, was that just in dry form, or in solution? And what concentration HCl did you use?vano - 20-8-2021 at 22:58

Sodium hydroxide was in solution, but trioxide is very slightly soluble in water. When i pour hydroxide solution in trioxide flask then it dissolved.
When i dried it it was like soap and i added concentrated HCl, but not much, because there is no many hydroxide and this amount was enough.
