Current passes through a solution of sodium chloride. In 1.00 second, 2.68×1016Na+ ions arrive at the negative electrode and 3.92×1016Cl− ions arrive at the positive electrode. Part A What is the current passing between the electrodes?

Answer : The current passing between the electrodes is,

Explanation :

First we have to calculate the charge of sodium ion.

where,

q = charge of sodium ion

n = number of sodium ion =

e = charge on electron =

Now put all the given values in the above formula, we get:

Now we have to calculate the charge of chlorine ion.

where,

q' = charge of chlorine ion

n = number of chlorine ion =

e = charge on electron =

Now put all the given values in the above formula, we get:

Now we have to calculate the current passing between the electrodes.

Thus, the current passing between the electrodes is,

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

the answer is 75.0%.
