Question

Wanna be brainliest or wanna be followed, please answer this appropriately.

Why is each metal having two ions?
Proper reason and explaination is required

Answer 1

Answer:

heavy metals' atoms can be poly valent...i.e., they show two valencies..it happens due to their electronic configuration with spdf....For more information about spdf follow me and ask the question again or better ask your physics teacher to explain it...teachers know students better than people on social media

Explanation:

please mark my answer the brainliest

Answer 2

Hey, the metals all have a almost half-filled subshell or a almost full subshell.

Hence , to gain more stability, these metals are creating the following ions.

These metals have more than two ions.

The names of the respective ions are given alongside.

For the first ion, the iupac coefficient is' ous' and for the second ion, the iupac coefficient is 'ic'.

The present study ion exchange of Pb(2+), Cu(2+), Fe(3+), and Cr(3+) on natural Greek clinoptilolite was examined in terms of selectivity toward the above heavy metals in single- and multicomponent solutions in batch systems.

Also examined are the influence of clinoptilolite on solution acidity and the effect of acidity on the ion exchange process.

Clinoptilolite increases solution acidity due to the exchange of H(+) cations with the cations initially present in its structure.

H(+) cations should be considered as competitive ones in ion exchange processes, and consequently ion exchange of metals is favored at high acidity values.

Cu(2+) and Cr(3+) are the most sensitive cations with respect to acidity.

Selectivity determination demonstrates that the selectivity at total concentration 0.01 N and acidity 2 in both single- and multicomponent solutions is following the order Pb(2+)>Fe(3+)>Cr(3+) > or =Cu(2+).

However, Cu(2+) shows remarkable changes in selectivity and generally its uptake and selectivity are increasing with time.

On the other hand selectivity in single metal solutions where acidity is not adjusted is following the order Pb(2+)>Cr(3+)>Fe(3+) congruent with Cu(2+)

Hope this helps you...
