Help Sodium Cyanide

[Schizoid]

Can Sodium Cyanide generates Hydrogen Cyanide without acid, How can i test it safely?

 

[Superfluous]

Sodium cyanide decomposes on contact with acids, acid salts, water, moisture, and carbon dioxide, producing highly toxic, flammable hydrogen cyanide gas.Sodium cyanide solution in water is a strong base; it reacts violently with acid and is corrosive. Sodium cyanide is incompatible with strong oxidants.

CDC link.

I have no idea how NaCN + CO2 can produce HCN as there is no H molecule present in either compound.

I would assume that decomposition is much slower with water than with HCl.

As to testing it safely, I have no idea.

Edit: I forgot to mention that HCN is highly soluble in water, so it may not be a suitable alternative to acids for creating HCN gas.

For those not familiar with chemical notation:

NaCN = Sodium Cyanide
HCN = Hydrogen Cyanide
HCl = Hydrochloric acid
