Electrolyte Solution: Understanding, Characteristics, and Types With Complete Examples - Do you know what is meant by electrolyte solution ??? If you don't know it, you are absolutely right to visit gurupendukasi.com. Because on this occasion here will review about the understanding of electrolyte solutions, the characteristics of electrolyte solutions, and types of electrolyte solutions along with examples in full. Therefore, let us consider the review below.
Electrolyte Solution
Definition of Electrolyte Solution
Electrolyte solution is a solution that can conduct electric current. In an electrolyte solution, the molecules break down (dissociate) into positive and negative electrically charged particles called ions (positive ions). The positive ion produced is called a cation and the negative ion produced is called an anion. The sum of the charges of positive ions and negative ions will be the same so that the charge of the ions in the neutral solution. These ions then conduct electricity.
Chemical changes in this solution are characterized by changes in color, the appearance of gas bubbles and the presence of sediment, and if tested with an electrolyte assay this solution is able to light a lamp. The more ions that are formed, the stronger the electrolyte properties of the solution.
Types of electrolyte solutions
Electrolyte solutions are divided into 3 which have their own characteristics as below:
1. Strong electrolyte solution
Strong electrolyte solution, which is a solution in which all molecules break down into ions (fully ionized). Because of the large number of electrically conducting ions formed, the conductivity is also strong. Generally a strong electrolyte solution is a salt solution.
Characteristics of Strong Electrolyte Solutions
Conducting electric current is strong or good
Perfectly ionized
The degree or degree of ionization (a) a = 1
If tested, strong electrolyte solutions have bright lights and many gas bubbles appear
Example :
Salt (NaCl, KCl, CuSO4 and KNO3),
Strong acids (HCl, HI, HBr, H2SO4 and HNO3), and
Strong bases (NaOH, Ca (OH) 2, Mg (OH) 2 and KOH)
The strong electrolyte decomposition reaction is written with a single arrow to the right. Examples of strong electrolyte reactions:
NaCl (aq) → Na + (aq) + Cl– (aq)
H2SO4 (aq) → 2 H + (aq) + SO4 2- (aq)
NaOH (aq) → Na + (aq) + OH– (aq)
2. Weak Electrolyte Solution
Weak electrolyte solution, which is a solution where not all molecules are ionized (imperfect ionization), so that only a few ions can conduct electricity.
Weaknesses of Weak Electrolyte Solutions
Poor or poor electrical conductors
Partially ionized
The degree or degree of ionisation (a) 0 <a <1
If tested, the electrolyte solution is weak and the lights are weak and little gas bubbles appear.
Examples of Weak Electrolyte Solutions
Weak acids (HCN, H3PO4, CH3COOH, and C2O3)
Weak Base (NH4OH, Al (OH3),
and Fe (OH) 3).
3. Non-electrolyte solution
Non-electrolyte solutions are solutions that cannot conduct electricity. Non-electrolyte solutions consist of substances that are dissolved in water but are not broken down into ions (not ionized). In solution, the non-electrolyte substance remains like a molecule with no electric charge. That is why this solution cannot conduct electricity.
Characteristics of Non-Electrolyte Solutions
Cannot be ionized
Cannot conduct electric current or insulator
The degree or degree of ionisation (a) a = 0
If tested, the Non Electrolyte Solution, does not ignite and does not emerge gas bubbles.
Examples of Non-Electrolyte Solutions
Urea = CO (NH2) 2
Glucose = C6H12O6
Sucrose = C12H22O11
Ethanol = C2H2OH
Example of a non-electrolyte solution reaction
C6H12O6 (s) C6H12O6 (aq)
