The anode is the negative electrode and so will be donating electrons to assist in this chemical reaction occuring. All reactions accept electrons as reactants. The key issue is the reduction potential Eo (+1.8V). This is greatest for the reaction:

Co3+ + e -> Co2+

Therefore this reaction has the greatest tendency to occur.

When a mixture containing cations of Analytical Groups I–III is treated with H2S in acidic solution, which cations are expected

Fantom [35]

Answer:

Analytical Groups I and II

Explanation:

Precipitation reactions happen when anions and cations in aqueous solution mix together to form an insoluble ionic solid which is now referred to as a precipitate.

Whether or not a type of reaction like that takes place can be determined by utilizing the solubility principles for common ionic solids.

Indicators change color in acids or bases. What are the colors of the pH balance

lozanna [386]

Answer:

}

the color of the pH balance is dark blue

Explanation:

A pH indicator corresponds to a substance that measures the pH of the solution in question. in the case of neutral substance the color that the solution takes is dark blue, if it is acidic it turns pink or red and basic of a green tone. Some examples of indicators: phenolphthalein, bromophenol blue, methyl red, among others.

Give an example of a state function and explain why it is a state function

inessss [21]

A specific state which is defined being a property without the path taken to achieve that state based on it, is understood as a state function.
While the functions whose value is based on the direction taken among two states are named direction or path functions, on the other hand.
The system's thermodynamic condition relates to the current material in temperature, pressure and quantity.
State functions rely only on certain requirements and not on how they have been achieved. State functions for an instance, involve entropy, density, enthalpy and internal energy.
They are known as state functions as they quantitatively define a thermodynamic system's equilibrium condition, regardless of how the system landed in that condition.
