A KClKCl solution containing 41 gg of KCl per 100.0 g of water is cooled from 70 ∘C to 0 ∘C. What happens during cooling? A solution containing 41 of per 100.0 of water is cooled from 70 to 0 . What happens during cooling? At 70 ∘C the solution is unsaturated, but by 0 ∘C the solution is saturated; therefore a precipitate will form. At 70 ∘C the solution is supersaturated, but by 0 ∘C the solution is unsaturated; therefore no precipitate will form. At 70 ∘C the solution is supersaturated; therefore a precipitate will form upon cooling. At 70 ∘C the solution is unsaturated, and at 0 ∘C the solution is also unsaturated; therefore no precipitate will form.
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.

A saturated solution is one in which a solvent has completely dissolved all of the solutes presents. This state occurs when the solution is in equilibrium, and no more solute can be dissolved in the solvent. Unsaturated solutions are solutions that do not contain the maximum amount of solute dissolved in the solvent. In other words, more solute can still be dissolved in the solvent, and the solution is not in equilibrium.
Saturated solutions can be easily identified by the fact that no undissolved solute remains in the solution. Unsaturated solutions, on the other hand, still have some undissolved solute present, indicating that more of the solute can be added and dissolved.
These two types of solutions have different properties and different implications for chemical reactions. Saturated solutions are generally more stable than unsaturated solutions, and therefore, different reactions will occur depending on the type of solution. For example, a saturated solution will produce a different amount of a product than an unsaturated solution when the same reactants are present.
