Copper(II) nitrate (Cu(NO3)2) itself is not a redox substance, as it does not undergo a change in oxidation states during typical reactions. However, in reactions involving copper compounds, such as when Cu(NO3)2 reacts with reducing agents, redox processes can occur. In those cases, copper may be reduced or oxidized, depending on the specific reactants involved. Thus, while Cu(NO3)2 can participate in redox reactions, it is not inherently a redox agent by itself.
The balanced chemical equation for the reaction between copper (Cu) and nitric acid (HNO3) is: 3Cu + 8HNO3 -> 3Cu(NO3)2 + 2NO + 4H2O According to the equation, 8 moles of HNO3 are required to react with 3 moles of Cu. Therefore, to react with 6 moles of Cu, you would need 16 moles of HNO3.
Yes, the reaction Zn + CuCl2 → ZnCl2 + Cu is a redox reaction. In this process, zinc (Zn) is oxidized as it loses electrons and is converted to ZnCl2, while copper ions (Cu²⁺) from CuCl2 are reduced as they gain electrons to form elemental copper (Cu). The transfer of electrons between zinc and copper ions characterizes the redox nature of the reaction.
The reaction is:Cu + 4 HNO3 = Cu(NO3)2 + 2 NO2 + 2 H2O
0.34-(-2.37)
To determine the overall voltage for the redox reaction involving the half-reactions ( \text{Mg}(s) \rightarrow \text{Mg}^{2+} + 2e^- ) and ( \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu}(s) ), you first need the standard reduction potentials. The standard reduction potential for ( \text{Cu}^{2+}/\text{Cu} ) is +0.34 V and for ( \text{Mg}^{2+}/\text{Mg} ) is -2.37 V. The overall voltage is calculated by subtracting the oxidation potential of magnesium from the reduction potential of copper: ( 0.34 , \text{V} - (-2.37 , \text{V}) = 2.71 , \text{V} ). Thus, the overall voltage for the redox reaction is 2.71 V.
Cu + HNO3 = Cu(NO3)2 + NO + H2O
To find the volume of 16M HNO3 required to react with 0.0214g of Cu metal, you need to calculate the moles of Cu. Then, using the balanced equation for the reaction between Cu and HNO3 (Cu + 4HNO3 → Cu(NO3)2 + 2NO2 + 2H2O), you can determine the moles of HNO3 needed. Finally, using the molarity of the HNO3 solution, you can calculate the volume in drops.
Cu(NO3)2 and H2 are formed
Sulfuric acid is commonly used in redox titrations because it is a strong acid and does not participate in the redox reactions. Nitric acid (HNO3) can act as an oxidizing agent itself, which can interfere with the redox titration process by introducing additional reactions.
The balanced chemical equation for the reaction between copper (Cu) and nitric acid (HNO3) is Cu + 4HNO3 -> Cu(NO3)2 + 2NO2 + 2H2O. From the equation, it can be seen that 1 mol of Cu reacts with 4 mol of HNO3. Therefore, to react with 2.0 mol of HNO3, 0.5 mol of Cu is needed. The molar mass of Cu is approximately 63.5 g/mol, so 0.5 mol of Cu would be equivalent to 31.75 grams.
The redox equation for the oxidation of copper iodide is: 2CuI -> 2Cu + I2
The balanced chemical equation for the reaction between copper (Cu) and nitric acid (HNO3) is: 3Cu + 8HNO3 -> 3Cu(NO3)2 + 2NO + 4H2O According to the equation, 8 moles of HNO3 are required to react with 3 moles of Cu. Therefore, to react with 6 moles of Cu, you would need 16 moles of HNO3.
Yes, the reaction between Zn and CuCl2 to form ZnCl2 and Cu is a redox reaction. Zinc (Zn) is oxidized to form Zn2+ ions, while copper (Cu2+) is reduced to elemental copper (Cu).

HNO3 is not used in redox titration because being a good oxidising ageant it oxidises the compound itself whereas HCL is a very volatile and it takes part in the reaction therefore H2SO4 is used in the reaction
H2SO4 is used in acidification of KMnO4 solution because it is a stronger acid compared to HCl or HNO3, which ensures complete dissociation of the acid and provides a higher concentration of H+ ions for the redox reaction to occur efficiently. Additionally, H2SO4 is not easily oxidized by KMnO4, unlike HCl or HNO3 which could interfere with the redox reaction.
