I want to know the answer to the following question:
What did Klaproth probably create when he dissolved pitchblende in nitric acid?
All the background I'm provided with is that "While he was working in his experimental laboratory in Berlin in 1789, Klaproth was able to precipitate a yellow compound (likely sodium diuranate) by dissolving pitchblende in nitric acid and neutralizing the solution with sodium hydroxide.". Is that enough to answer the question?
Answer: yes
