Pretty much all said in title.  Stannic chloride  :rarrow: Stannic chloride pentahydrate.

Not only SnCl4, but many other salts, like Fe(NO3)3, AlCl3, ecc. The reaction you mention is the hydrolisys:
Sn4+ + nH2O <--> [Sn(OH)n](4-n)+  0<=n<=4
Fe3+ + nH2O <--> [Fe(OH)n](3-n)+ ;  0<=n<=3
So it's an equilibrium; lowering the pH displaces the reaction towards the left. Those compounds are infact synthesized in strongly acidic solutions.
