Definition of Non-electrolyte
Non-electrolytes are those that cannot conduct electricity when dissolved in water. The more the number of ions, the stronger the conductivity. And while a solution that cannot conduct an electric current is caused by the substances that remain intangible in neutral molecules.
Based on the conductivity of electrolyte solution is divided into two, namely strong electrolytes with a large conductivity. For example in strong acid solutions, strong bases and salt. the second is a weak electrolyte, which is a solution with weak conductivity.
Classified as weak electrolytes:
Weak acids, such as: CH3COOH, HCN, H2CO3, H2S and others
Weak bases such as: NH4OH, Ni (OH) 2 and others
Salts that are difficult to dissolve, such as: AgCl, CaCrO4, PbI2 and others
Example :
CH3COOH, HCOOH, HF, H2CO3, and NH4OH
Electrolyte solutions can be sourced from ionic compounds (compounds that have ionic bonds) or polar covalent compounds (compounds that have polar covalent bonds)
Definition of Electrolyte Solution
Solution is an interagency substance which has no boundary plane and is homogeneous in all parts of the mixture. The components of the solution are solvents and dissolved substances. Electrilit is a substance that when dissolved in water will get a solution that can produce electric current.
Classified as this type for example:
Urea (CO (NH2) 2) solution
Sucrose Solution
Sugar solution (C12H22o11)
Glucose Solution (C6H12O6)
Alcohol solution (C2H5OH)
Electrolyte Solution Forming Compounds
Compounds in the solution can conduct electric current in the form of ion compounds and polar covalent compounds, because these compounds can be ionized when dissolved in water.
Ion compound
Ionic compounds have a composition of several ions which have a solid and dry form. The ions making up the ion compound in the solvent will move freely so that the ion solution can conduct an electric current. Ionic compounds which are in the form of crystals, the ions cannot move freely so they cannot conduct electric current. For example NaCl, KCl, NaOH and KOH.
Polar Covalent Compound
Polar covalent compounds if dissolved in water, they will break down to turn into ions. This is because the covalent bonds in these compounds break easily in the ait solvents and produce ions. For example hydrochloric acid (HCl), Ammonia (NH3).
How to Electrolyte Solution Conducting Electric Current
Electrolyte solutions exist in ions which have different charges and move freely. If an electric current is connected, the cation moves towards the cascade and the anion moves towards the anode so that the electric current can flow in a system.
Non-electrolyte example
Below are included which are non-electrolyte solutions, namely:
Sucrose Solution
Alcohol solution
Glucose Solution
Urea Solution
General Dissolution Process
Solution is a phase that every day is around us. A homogeneous system that contains two or more substances whose individual components cannot be distinguished physically is called a solution, while a heterogeneous system is called a mixture.
Usually the term solution is considered as a liquid containing solutes, for example solids or gases in other words the solution is not just limited to liquids.
The components of the solution are of two types, solvents and solutes, which can be exchanged depending on the amount. Solvents are the main component contained in large amounts, while the minor components are solutes.
The solution is formed by mixing two or more pure substances whose molecules interact directly in a mixed state. All gases can be mixed with each other, so the gas mixture is a solution. The dissolution process can be illustrated as shown above.
Types of Solutions
Gas in the gas - the entire gas mixture
Gas in liquid - oxygen in water
Liquid in liquid - alcohol in water
Solids in liquid - sugar in water
Gas in solids - hydrogen in palladium
Liquid in solids - Hg in silver
Solids in solids - alloys
