FeCl3 will combine wid water to form Fe(OH)3 a weak base and HCl a strong acid....so its ph is less than 7..
u r absolutely right acctually fecl3 will break like fe3+ and cl- and water as h+ and oh-and positive attract negative so it will combanine and form hcl and a weak base plz rate me
FeCl3 is the salt of weak base Fe(OH)3 with strong acid HCl ...
that is why it is acidic..
alternatively, when we put FeCL3 in aqueous solution, FeCl3 dissociates as
FeCL3 ------> Fe(3+) + 3Cl(-1)
this Fe3+ combines with the OH- present in the water ( water also dissociates to a very small extent)
H2O <-----> H(+) + OH (-)
Fe(3+) + 3OH (-) ------> Fe(OH)3
Fe(OH)3 ppt is obtained...
hence, in the aqueous solution, excess of H+ ions are present..
this makes the solution acidic..
hope it helps....
