What happens if you add benzoic acid to nitric acid with a concentrated sulfuric acid catalyst?
NIitration on the meta- position of benzoic acid will happen.
Why add the nitric acid?
Nitric acid (HNO3), also known as aqua fortis and spirit of nitre, is a highly corrosive and toxic strong mineral acid which is normally colorless but tends to acquire a yellow cast due to the accumulation of oxides of nitrogen if long-stored. Ordinary nitric acid has a concentration of 68%. When the solution contains more than 86% of it, it is referred to as fuming nitric acid. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as white fuming nitric acid or red fuming nitric acid, at concentrations above 95%. Nitric acid is also commonly used as a strong oxidizing agent.
How do you safely mix hydrochloric acid and nitric acid?
In a fume hood, using gloves, add acids slowly.

What you can mix in nitric acid?
Nitric acid is very corrosive and a very strong acid. You can mix in water but remember add acid to the water and not water to the acid. When mixed with concentrated sulfuric acid it forms an excellent nitrating mixture for organic compounds. When doing a chloride titration with Silver Nitrate, Nitric acid is used to acidify and help the titration. There are many other uses also which involve mixing chemicals with nitric acid.
Why do iron filings do not sink when placed slowly on the surface of the water?
Surface tension supports the filings in the same way as a pond skater. Add a drop of detergent and the meniscus is broken down and the filings fall to the bottom

How do you separate table salt aluminum filings iron filing?
Use a magnet to remove the iron filings. The add water to dissolve the salt, and the aluminum filings will settle to the bottom of the container. Pour that salt water into a pan, heat it and evaporate the water, leaving the salt in the pan.
