Q

The negative plate of an Edison-type storage cell is:

🔍 Key Concepts

• Composition and construction of an Edison (nickel–iron) alkaline storage cell • Difference between positive and negative plates in nickel–iron batteries • Typical electrolyte used in Edison cells vs what materials are used for plates

💭 Think About

• First, recall what metals give the nickel–iron (Edison) cell its name, and which one is associated with the negative plate. • Think about which listed substances are realistic plate materials and which are more likely electrolytes or compounds not used as plates. • Eliminate any options that do not match the known chemistry of an alkaline nickel–iron storage battery.

✅ Before You Answer

• Verify which material in a nickel–iron cell is associated with the negative electrode (plate). • Check whether any of the options describe the active material form (e.g., powdered, oxide, etc.) that is used on the negative plate. • Confirm that you are not confusing electrolyte components (like potassium hydroxide) with plate materials.
