Capitolo 4, Problema 105a
Suppose you have 3.00 g of powdered zinc metal, 3.00g of powdered silver metal and 500.0 mL of a 0.2 M copper(II) nitrate solution. (a) Which metal will react with the copper(II) nitrate solution?
Guida verificata passo dopo passo1
Identify the metals involved in the reaction: zinc (Zn) and silver (Ag).
Write the balanced chemical equations for the possible reactions of each metal with copper(II) nitrate (Cu(NO_3)_2).
For zinc: Zn + Cu(NO_3)_2 \(\rightarrow\) Zn(NO_3)_2 + Cu. Zinc can displace copper from the solution because it is more reactive.
For silver: Ag + Cu(NO_3)_2 \(\rightarrow\) No reaction. Silver is less reactive than copper and cannot displace it from the solution.
Conclude that zinc will react with the copper(II) nitrate solution, while silver will not.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Reactivity of Metals
The reactivity of metals is determined by their ability to lose electrons and form positive ions. In a displacement reaction, a more reactive metal can displace a less reactive metal from its compound. Understanding the reactivity series of metals helps predict which metal will react with a given solution.

Transition Metals
Displacement Reactions
Displacement reactions occur when a more reactive element displaces a less reactive element from a compound. In this scenario, zinc and silver are compared to copper(II) ions in the solution. The metal that is higher in the reactivity series will replace the copper ions, leading to the formation of a new compound.

Molarity and Stoichiometry
Molarity is a measure of concentration, defined as moles of solute per liter of solution. In this question, the concentration of copper(II) nitrate is given, which is essential for calculating the number of moles available for reaction. Stoichiometry allows us to relate the amounts of reactants and products in a chemical reaction, helping to determine the limiting reactant.

Citric acid, C6H8O7, is a triprotic acid. It occurs naturally in citrus fruits like lemons and has applications in food flavouring and preservatives. A solution containing an unknown concentration of the acid is titrated with KOH. It requires 23.20 mL of 0.500 M KOH solution to titrate all three acidic protons in 100.00 mL of the citric acid solution. Write a balanced net ionic equation for the neutralization reaction.
