Write the chemical formula for the anion present in the aqueous solution of cuso4.

Answer : The chemical formula for the anion present in the aqueous solution of is,

Explanation :

The chemical formula of copper sulfate is, .

The dissociation reaction of in aqueous solution will be:

From the reaction we conclude that, 1 mole of dissociate in solution to give 1 mole of ion (copper ion) and 1 mole of ion (sulfate ion).

In the reaction, ion (copper ion) is a cation and ion (sulfate ion) is an anion.

Hence, the chemical formula for the anion present in the aqueous solution of is,

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
