What reaction can occur, if any, when the following experiments are carried out under standard-state conditions? (a) A strip of zinc is dipped into an aqueous solution of Pb(NO3)2.

Key Concepts

Redox Reactions

Redox reactions involve the transfer of electrons between substances, leading to changes in oxidation states. In the context of the question, zinc (Zn) can act as a reducing agent, losing electrons, while lead ions (Pb^2+) can gain electrons, thus being reduced. Understanding the principles of oxidation and reduction is essential for predicting the outcome of the reaction.

Standard-State Conditions

Standard-state conditions refer to a set of specific conditions (1 atm pressure, 25°C temperature, and 1 M concentration for solutions) under which the properties of substances are measured. These conditions provide a consistent framework for comparing thermodynamic data and predicting the feasibility of reactions, such as the one between zinc and lead nitrate.

Activity Series of Metals

The activity series is a list of metals ranked by their ability to displace other metals from solutions of their ions. Zinc is more reactive than lead, meaning it can displace lead ions from the solution. This concept is crucial for determining whether a reaction will occur when zinc is placed in a solution of Pb(NO3)2.
