Can hydrocholoric acid be used as a replacement of Picric acid?

04 April 2019 1 6K Report

I wanted to test the ability of bacteria to produce Hydrogen cyanide. In the procedure, different scientist have used Picric acid but we can't use this acid in our lab so i want to know if HCL can be used as a replacement of Picric acid or suggest me if you know any other replacement.

Regards!

Because pKa of HCN is 9.31 (20 °C)/ 9.22 (25 °C) you can use NaHCO3 (aq) as acid ( pK1 for carbonic acid: 6.35 ).
