Question

Equivalent weights of Na2CO3 and Al2(SO4)3
are respectively
1) 62, 40 2) 53, 57
3) 46, 83.5 4) 61, 48

Answer 1

Answer:

Option (2)

Explanation:

• Equivalent weight of acid = Molar mass ÷ No. of H+ ions replaced by base

• Equivalent weight of base = Molar mass ÷ No. of OH- ions replaced by acid

1. Equivalent weight of Na2CO3 = 106 ÷ 2

= 53

2. Equivalent weight of Al2(SO4)3 = 342 ÷ 6

= 57

Hope this helps you :)
