Solution is prepared by adding 18 mL of 0.200 M Fe(NO3)3and 2 mL of 0.0020 M KSCN. Calculate the initial concentrations of Fe3 and SCN-in the solution

Answer : The initial concentration of and in the solution are, 0.200 M and 0.0020 M respectively.

Explanation :  Given,

Concentration of = 0.200 M

Concentration of = 0.0020 M

As, 1 mole of   dissociate then it gives 1 mole of ion and 3 moles of ion.

So, 0.200 M of   dissociate then it gives 0.200 M of ion and (3×0.200 M) of ion.

and,

As, 1 mole of   dissociate then it gives 1 mole of ion and 1 mole of ion.

So, 0.0020 M of   dissociate then it gives 0.0020 M of ion and 0.0020 M of ion.

Thus, the initial concentration of and in the solution are, 0.200 M and 0.0020 M respectively.

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
