Dear Learned Ones…
Several years ago when confronted with the assertion that we couldn’t store nitric acid and acetic acid together (or nitric acid n a wooden shelf) because they were incompatible I conducted an experiment.
<![if !supportLists]>1. <![endif]>I took glacial acetic acid and added concentrated nitric acid while stirring, anticipating a reaction… nothing happened. It didn’t get hot, cold or have gas evolve
<![if !supportLists]>2. <![endif]>So after reaching a 50:50 mix I began heating while stirring (did I mention this was in a hood with proper PPE and a written procedure way back in the early 1990’s)
<![if !supportLists]>3. <![endif]>I got in boiling and still there was no obvious reaction.
<![if !supportLists]>4. <![endif]>Now I added pencil shavings in small amounts in the belief it would catch on fire…
<![if !supportLists]>5. <![endif]>Nothing apparent happened.
<![if !supportLists]>6. <![endif]>So I added more.
<![if !supportLists]>7. <![endif]>Finally after 20 minutes mild boiling with concentrated nitric, glacial acetic and wood pieces I squirted just a drop of acetone a definitely got the reaction I expected (flame)
Does anyone have a real world experience where nitric acid caused an unwanted reaction with acetic acid or a wooden shelf?
