Zinc And Copper Nitrate Balanced Equation

The balanced equation is zn s cu no3 2 aq cu s zn no3 2 aq is the balanced equation correct.

Zinc and copper nitrate balanced equation.

Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. A dark coating of copper metal appears on the zinc within two minutes and when 45 minutes have elapsed there is a thick coat of copper metal powder on the zinc strip and the blue color of the solution has lightened considerably. Concentrated nitric acid reacts with copper and produce copper nitrate cu no 3 2 nitrogen dioxide no 2 gas and water as products in this reaction copper is oxidized to its 2 oxidation state while nitric acid is reduced to nitrogen dioxide. Identify the oxidation number of each element in the reaction.

After the reaction color of the solution which contains cu no 3 2 is blue. Half equation ref 9 is a reduction because electrons are accepted. What is the reducing agent. When zinc metal is immersed in a solution of 0 1 m aqueous copper ii sulfate solution c opper metal plates out on the zinc the solution is initially blue in color.

Zinc reduces the copper ion and the copper ion oxidizes the zinc. Examples of complete chemical equations to balance. Zinc is well known for its immune modulating effects but copper plays a role too especially the copper to zinc ratio. Reaction stoichiometry could be computed for a balanced equation.

Clearly copper atoms have lost electrons while a combination of hydronium ions and nitrate ions have accepted them. A balanced copper to zinc ratio which is between 0 7 to 1 0 based on the studies discussed here plays a role in maintaining the immune system helping resist infectious diseases and it has the potential to be used as an. Accordingly we can refer to the nitrate ion or nitric acid hno 3 as the oxidizing agent in the overall reaction. Enter either the number of moles or weight for one of the compounds to compute the rest.

Zn s cu no 3 2 aq rarr zn no 3 2 aq cu s zinc is a more active metal than copper it lies higher up the activity series. Fe cl 2 fecl 3. What is the oxidizing agent.
