You have to show you attempts at solving the problem to receive help, this is a forum policy.

Tris is usually sold as a base, but I have on occasion seen it sold as its hydrochloride salt, which is the conjugate acid of Tris base.  It is a commonly used buffer in biochemistry, with certain things to recommend it, as well as some shortcomings.

Tris is a primary amine (RNH₂), Tris.HCl RNH₃Cl) is a salt of this amine. In reactions treat them analogously to NH₃ and NH₄Cl.
