Question

How do you fully dissolve a power (e.g. sodium carbonate) into distilled water?

Answer 1

Sodium carbonate is generally represented by the chemical formula $N{{a}_{2}}C{{O}_{3}}$which can also be known by some other names called soda ash, washing soda and soda crystals. It is generally kept in the category of inorganic compounds.

Complete answer:
Sodium carbonate is found in many hydrated forms most of them are white in color which is soluble in water which yields an alkaline solution in water. Sodium carbonate is generally extracted from the ashes of wood that’s why it is also known as soda ash.
Distilled water is the purest form of water in which no ions are present and we get the distilled water from the distillation process. Hence we can easily dissolve the sodium carbonate in distilled water as it is soluble in aqueous solution and when we dissolve it in distilled water then sodium bicarbonate gets dissociate into ions known as cation and anion and the reaction can be shown as follows:
$N{{a}_{2}}C{{O}_{3}}+{{H}_{2}}O\to 2N{{a}^{+}}+C{{O}_{3}}^{2-}$
Here the ion which is positive in charge is cation and ion which carries negative charge is said to be anion. Hence we can say that sodium bicarbonate can be easily dissolved in distilled water as it dissociates into ions.

Note:
The solubility of a substance in a solvent is defined as the total amount of the solute dissolved in the solvent at equilibrium and the solubility product constant is defined as an equilibrium constant which provides insight into the equilibrium between the solid solute and its constituent ions dissociated in the solution.
