Question

Fe(OH)3 + H2SO4------------> Fe2(SO4)3 + H2O What is the valency of iron in the reaction above? 2 3 4 6

Answer 1

Answer:

The valency of Iron is 3...

Answer 2

Given:

Fe(OH)3 + H2SO4------------> Fe2(SO4)3 + H2O

To find:

Valency of Fe ?

Solution:

$\boxed{ \bf Fe(OH)_{3} + H_{2}SO_{4}\rightarrow Fe_{2}(SO_{4})_{3} + H_{2}O}$

So, let's take a look at the reactant side:

• We will do criss-cross method to determine valency.

• The subscript under OH , will be transferred to valency of Fe and subscript under Fe will be transferred to valency of OH.

• So, Fe has valency 3 and OH has valency 1.

Now, let's take a look at the product side:

• Perform the same steps with SO4 and Fe.

• So, Fe has valency 3 and SO4 has valency 2.

Hope It Helps.
