Question

What is the solubility of `NH_3` at 10°C?

Answer 1

Well, usually high ....

Explanation:

The concentrated ammonia that you use from a Winchester as an aqueous solution is approx. `15*mol*L^-1` with respect to ammonia. This is the stuff that really pen and inks when you use it as a reagent, and is approx. `30%` `"w/w"` with respect to ammonia. The density of this solution is approx. `0.88*g*mL^-1`. Ammonia is a very water-like solvent capable of hydrogen bonding, that has considerable water solubility on this account.

You can search the link for actual values but at `10` `""^@C` the solubility of the gas should be greater than that quoted....
