In order to determine the moles of edta that reacted with the calcium ions, we need to use the volume of the edta solution that was used in the reaction.
The volume of edta solution can be used to calculate the moles of edta that reacted with the calcium ions using the formula: moles of edta = (volume of edta solution) x (concentration of edta solution).
Once we have determined the moles of edta that were present in the solution, we can then calculate the moles of edta that reacted with the calcium ions.
This can be done by subtracting the moles of unreacted edta from the total moles of edta used in the reaction.

the conversion of 4-pentanoylbiphenyl to 4-pentanylbiphenyl with hydrazine and potassium hydroxide is an overall of carbon? a. oxidation b. not a redox c. reduction
The conversion of 4-pentanoylbiphenyl to 4-pentanylbiphenyl with hydrazine and potassium hydroxide is a reduction . Option c. is correct.
Because it involves the addition of hydrogen atoms to the carbon atoms in the molecule, resulting in a decrease in the oxidation state of the carbons. During the reaction, hydrazine acts as a reducing agent and reduces the ketone group (-[tex]CO^-[/tex]) to an alcohol group (-[tex]CH_2OH[/tex]). This reduction results in the conversion of the carbonyl carbon from sp2 hybridization to sp3 hybridization, resulting in the formation of a new C-H bond.
Therefore, the reaction involves a gain of electrons by the carbonyl carbon, and a reduction of the ketone functional group. There is no simultaneous oxidation of any other species in the reaction.
Therefore, the reaction is a reduction and not an oxidation or a non-redox reaction. Hence, option c. is correct.
