  We present a study of the superconducting properties of the candidate
topological superconductor Ti_(3)Sb. Electrical transport measurements show
zero resistance with a T_(c,onset) of ~ 5.9 K with a transition width
{\Delta}T_c~ 0.6 K. The superconducting phase boundaries as derived from
magneto-transport and magnetic susceptibility measurements agree well. We
estimate an upper critical field Bc2(0)~4.5 T. A Ginzburg-Landau (GL) analysis
yields values of the coherence length and penetration depth of {\zeta} = 6.2 nm
and {\lambda} = 340 nm, respectively, and a GL parameter ~ 55, indicating
extreme type-II behavior. Furthermore, we observed a step height in the
specific heat ({\Delta}C_e)/({\gamma}T_c )~1.61, a value larger than the
Bardeen-Cooper-Schrieffer (BCS) value of 1.43, suggesting modest coupling.
Measurements of the temperature dependence of the London penetration depth via
the tunnel-diode oscillator (TDO) technique down to ~ 450 mK show a full
superconducting gap, consistent with a conventional s-wave gap structure.
