Question

What do you observe when caustic soda solution is added
to the following solution, first a little and then in excess:
(a) FeCl3,
(b) ZnSO4,
(c) Pb(NO3)2,
(d) CuSO4 ?
Write balanced equations for these reactions.​

Answer 1

Answer:

Explanation:

i)FeCl3+3NaOH→Fe(OH)3+3NaCl

ii)NaOH+ZnSO4→Na2SO4+Zn(OH)2

iii)2NaOH+Pb(NO3)2→2Na(NO3)+Pb(OH)2

iv)2NaOH+CuSO4→Na2SO4+Cu(OH)2
