Question

The diagram shows the setup of an experiment. A few observations of the experiment are listed in table below the diagram.

Experimental Observations

1. Color of solution turned blue
2. Shiny hair like crystals deposited on the copper strip

Which of the following is the correct explanation for one of the given observations?

Observation 1 is a result of silver ions moving into the solution.

Observation 2 is a result of nitrate ions moving into the solution.

Observation 1 is a result of silver ions changing their oxidation state.

Observation 2 is a result of silver ions changing their oxidation state.

Answer 1

Observation 2 is a result of silver ions changing their oxidation state.

Step-by-step explanation:

Silver is reduced and forms silver precipitate. Observation 1 is a result of coppe being oxidized and forming copper nitrate
