Question

What mililiter of concentrated nitric acid is required to prepare 2.0 L of aquaregia?​

Answer 1

Hey,

Concentrated HCl is typically 35%, while concentrated nitric acid is 65%. It's easier to use the volume ratio of 4 parts concentrated hydrochloric acid to 1 part nitric acid. Generally, only small volumes of aqua regia are prepared at a time, using 8 mL HCl and 2 mL HNO3 for a total volume of 10 mL.

Answer 2

Aqua regia is a mixture of concentrated nitric acid and concentrated hydrochloric acid at a ratio of 4:1.

According to the question;

We have to prepare 2 litre Aqua regia or 2000 ml Aqua regia.

Let the variable = x

Amount of HCl in the solution=x

Amount of HNO3 in the solution=4x

4x+x=2000

5x=2000

x=400

So,the amount of the HNO3 in the given Aqua regia solution is (4×400)=1600 ml(answer.)
