Question

will the soliutions of these salts be acidic, basic or neutral?
1)FeCl
2)CaBr2
3)NaF

Answer 1

i think your first option might be FeCl3 because FeCl doent exist

the principal involved in this is

salts which are obtained from week base strong acid will be acidic in natire

salts which are from strong acid and strong base is nuetral and

salts which are from strong base week acid will be basic

1)

FeCl3 is acidic

lets see how it formed

Fe(OH)3 (week base) + HCl (strong acid ------> FeCl3

2)

CaBr2 is nuetral

Ca(OH)2 (strong base) + HBr (strong acid) ---> CaBr2

3)

NaF is basic

NaOH (strong) + HF (week) ---> NaF
