Answer is: <span>ch3co2h; acetic acid.
</span><span>An Arrhenius acid is a
substance that dissociates in water to form hydrogen ions or protons.
</span>Acetic acid dissociate in aqueous solution to form hydrogen ions (H⁺) and acetic anion (CH₃COO⁻).
<span>Balanced chemical reaction (dissociation):
CH</span>₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
The denaturing of proteins is irreversible. For example, eggs cannot be unboiled. Other reactions, such as the formation of carbonic acid, are reversible.
Answer:
The water ligands surrounding the cobalt metal center are being replaced by ethylenediamine and chloride ligands which results in a different crystal field splitting. Thus, the energy associated with electron transitions between the do-orbitals will differ for the two compounds showing a color change.
Explanation:
The five d-orbitals are usually degenerate. Upon approach of a ligand, the d-orbitals split into two sets of orbitals depending in the nature of the crystal field.
The magnitude of crystal field splitting is affected by the nature of the ligand. Ligands having filled p-π orbitals such as ethylenediamine lead to greater crystal field splitting.
The change in the colour that takes place when ethylenediamine is added to the solution of cobalt(II) chloride occurs due to a different crystal field splitting pattern. Thus, the energy associated with electron transitions between the d-orbitals now differ for the two compounds showing a color change.
