Which term refers to the process by which ions that have entered solution are kept in solution?
2 answers:
Answer : The correct option is, hydration
Explanation :
Hydration : It is a process in which the ion or substance combines with water and kept in the solution. In the hydration process the solvent is water molecule.
For example : When the sodium chloride is dissolved in the water then the positive sodium ion get surrounded by the water molecule through their oxygen ends and the negative chloride ion get surrounded by the water molecule through their hydrogen ends.
Dissociation : It is a process in which the compound splits or dissociates into to two or more smaller ions, atoms or particles.
Electrolyte : it is a process in which the a molecule is completely dissociates into their respective ions in the aqueous solution.
Ionization : It is a process in which a molecule acquire a positive or negative charged by the gaining or losing electrons.
Hence, the correct option is, hydration.

Answer:
The advantages described below
Explanation:
Advantages of a balanced chemical equation versus word equation:
- easier to read: chemical equations typically only take one line and they include all the relevant information needed. They are short-hand notations for what we describe in words.
- balanced chemical equations show molar ratio in which reactants react and the molar ratio of the products. Those are coefficients in front of the species. This is typically not included in a word equation, for example, hydrochloric acid reacts with potassium hydroxide. The latter statement doesn't describe the molar ratio and stoichiometry.
- includes relevant information, such as catalysts, temperature and pressure above the arrow in the equation. We wouldn't have this in a word equation most of the time.
- shows the stoichiometry of each compound itself, e. g. if we state 'ammonia', we don't know what atoms it consists of as opposed to
.
- includes states of matter: aqueous, liquid, gas, solid. This would often be included in a word equation, however.
