Question

Copper sulphate penta hydrate What substances? Deliquescent or Hygroscopic

Answer 1

Answer:

1) Copper(II) sulfate pentahydrate,  $CuSO_{4} .5H_{2} O$, on the other hand, is a well known efflorescent substance.

2) The pentahydrate is blue in color. When you expose it to air, it will start losing water of hydration through evaporation and form a layer of anhydrous copper(II) sulfate,  $CuSO_{4}$, which is pale green in color.

Answer 2

Correct question is given as:

A) Write about copper sulphate pentahydrate.

B) Differentiate- Deliquescent and Hygroscopic.

Answer of the following questions are written below-

A)

• Copper sulphate pentahydrate is a blue crystalline inorganic compound with the chemical formula CuSO₄ₓ, where x can range from 0 to 5 and it is known to be as most common sulphate salt of copper.

• It is used as an antidote for phosphorus poisoning as well as can also be used to prevent the growth of algae.

B)

• The water soluble substance which occupy moisture from the air and later, dissolve on the absorbed moisture to transform into liquid taste are termed as Deliquescent substances.

• While the substances which occupy moisture from air, and still do not change their state are known to be as Hygroscopic substances.
