Answer:
The molarity of the solution is 1.1
Explanation:
Molarity is a measure of the concentration of that substance that is defined as the number of moles of solute divided by the volume of the solution.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:
Molarity is expressed in units
In this case
- number of moles of solute= 0.564 moles
- volume= 0.510 L
Replacing:
Solving:
molarity= 1.1
<u><em>The molarity of the solution is 1.1 </em></u><u><em></em></u>
Answer: The value of for the half-cell reaction is 0.222 V.
Explanation:
Equation for solubility equilibrium is as follows.
Its solubility product will be as follows.
Cell reaction for this equation is as follows.
Reduction half-reaction: ,
Oxidation half-reaction: ,
= ?
Cell reaction:
So, for this cell reaction the number of moles of electrons transferred are n = 1.
Solubility product,
=
Therefore, according to the Nernst equation
At equilibrium, = 0.00 V
Putting the given values into the above formula as follows.
=
= 0.577 V
Hence, we will calculate the standard cell potential as follows.
= 0.222 V
Thus, we can conclude that value of for the half-cell reaction is 0.222 V.
