Question

The speeds of the following ions are in the following order:a. H+ greater than OH- greater than Cu2+

b. H+ lesser than OH- greater than Cu2+

c. H+ lesser than OH- lesser than Cu2+

d. H+ greater than OH- lesser than Cu2+​

Answer 1

The order of speed of given ions

Explanation:

Option (a)  H+ greater than OH- greater than Cu2+

• Ionic mobility of an ion is an extent of movement of ion in solution.
• Ionic mobility of ion depend on their size.
• Size of hydrogen ion is smallest among all three ions, therefore it has maximum mobility.
• Whereas, size of Cupric ion is largest among the given ions, so it will have minimum mobility.
• The correct order of speed of the following ions will be:

$H^{+} > OH ^{-} >Cu^{+2}$

Answer 2

Answer:

Ionic mobility of an ion is an extent of movement of ion in solution.

Ionic mobility of ion depend on their size.

Size of hydrogen ion is smallest among all three ions, therefore it has maximum mobility.

Whereas, size of Cupric ion is largest among the given ions, so it will have minimum mobility.

The correct order of speed of the following ions will be:

H^{+} > OH ^{-} > Cu^{+2}H

+

>OH

−

>Cu
