By Raj Vimal|Updated : October 10th, 2022

(A) 45

(B) 63

(C) 90

(D) 126

The equivalent weight of oxalic acid in C2 H2 O4 ⋅2H2 O is 63. The oxalic acid's molecular weight (C2 H2 O4 ) is 90. However, since Oxalic Acid also contains two molecules of water, its molecular weight is two. (C2 H2 O4 ⋅2H2 O) = 126. We have described the answer below.

Equivalent Weight of Oxalic Acid

Now, Equivalent weight = Molecular weight/Basicity,

Therefore, Equivalent Weight = 126/2 = 63 (As 2 is the basicity)

Oxalic Acid releases two H+ ions when anything is basic.

The uses of Oxalic acid are mentioned below.

  • It serves as a mordant during the dyeing process.
  • Rust can be removed with it.
  • It is a crucial reagent in the study of lanthanides.
  • Marble sculptures are treated with it to make them gleam.
  • It is employed in bleaches and the production of dye.
  • It is applied to clean up stains from food and pen.
  • In order to develop photographic film, it is used.

Summary:

The Equivalent weight of oxalic acid in C2 H2 O4 ⋅2H2 O is? (A) 45 (B) 63 (C) 90 (D) 126

The equivalent weight of oxalic acid in C2 H2 O4 ⋅2H2 O is 63. As per the options available here, the correct option is option B. It is used to eliminate the calcium deposit during wastewater treatment.
