Question

Balance al2so4 -
Na OH
=aloh3 +na2so4
​

Answer 1

Here is the chemical equation.

Al2(SO4)3+NaOH=Al(OH)3+Na2SO4

First of all equal the no. of atoms on both side of the equation.

Reactants            =         Products  

Al            2           =              Al            1 X 2 = 2

SO4        3           =             SO4          1 X 3 =3  

Na      1 X 6 = 6   =              Na           2 X 3 =6

OH      1 X 6=6    =              OH           2 X 3 = 6  

Balanced equation:

Al2(SO4)3 + 6NaOH ------------->2Al(OH)3 + 3Na2SO4
