Question

MINUTES SECONDS
10. When NaCl is
decomposed by the given
process Na+ ions will get
attracted to which pole?
UA
9-12 V
Nad
HO
electrical decomposition of
NaCl will not take place
O towards negative pole
towards positive pole
since the solution of NaCl
contains water so water
only will decompose​

Answer 1

Answer:

NaCl is doped with 10

−3

mol % of SrCl

2

.

100 moles of NaCl are doped with 0.001 moles of SrCl

2

.

1 mole of NaCl is doped with

100

0.001

=10

−5

moles of SrCl

2

or 10

5

moles of Sr

2+

cations.

One Sr

2+

ion creates one cation vacancy.

10

−5

moles of Sr

2+

will create 10

−5

moles of cation vacancies which correspond to 10

−5

×6.023×10

23

=6.023×10

18

cation vacancies per mole of NaCl.

Answer 2

Answer:

to attract it to negative pole then add some carbon
