Iron and Copper Reactions

The video tutorial explains the single displacement reaction between iron (Fe) and copper sulfate (CuSO4). It describes how iron replaces copper, forming iron sulfate (FeSO4) and copper (Cu). The tutorial discusses the charges of ions involved, the electron transfer process, and the role of the activity series in predicting metal reactivity. The activity series helps determine which metals can displace others based on their reactivity levels.

What type of reaction occurs when iron reacts with copper sulfate?

What is the purpose of the activity series in single displacement reactions?

• To determine the solubility of compounds

• To predict the reactivity of metals

• To measure the pH of solutions

• To calculate the molar mass of elements

Why can't copper displace iron in the reaction with copper sulfate?

• Copper forms a stronger bond with sulfate
