Why does salt solution conduct power, while sugar solution doesn’t?

Salt solution such as sodium chloride (NaCl) conducts an electric existing because it has ions in it that have actually the flexibility to relocate about in solution. These ions are developed when sodium chloride dissolves in pure water to produce sodium (Na+) and chloride ions (Cl–).

You are watching: Why does sugar water not conduct electricity

When you insert the electrodes of a conductivity tester in the salt solution, the positive sodium ions usually move to the negative electrode, while the negative chloride ions relocate to the positive electrode. This movement of ions to opposite ends of the electrodes enable electric existing to circulation with the solution.

On the various other hand also, sugar solution does not conduct an electric current because sugar (C12H22O11) dissolves in water to produce sugar molecules. These sugar molecules are generally neutral (not charged), and also so are unable to move to the opposite ends of the electrodes choose the ions.

Here is a version that illustrates why NaCl conduct electrical power as soon as liquified in water.

Salt solution conducts electricity

Can deionized water conduct electricity?

Deionized water is water in which chemists usage a method called ion exchange to remove or exadjust the dissolved ions in it. Once these ions are removed deionized water is a poor conductor of electrical power.

Why can’t electrons flow with deionized water to make it conduct?

As it presently stands, nature has made it such that naked electrons can’t circulation via water or options, yet ions can. So, for water or any type of solution to conduct electricity, mobile ions must be present in it.

So, from our previous discussion of sugar and also salt solutions, you deserve to tell that some chemicals disresolve (break apart) in water to develop ions, while others disresolve to develop neutral molecules. When a salt dissolves and develop ions, we contact the process dissociation. Because of this, we can say that, sodium chloride dissolves and also dissociates, while sugar dissolves without dissociation.

What’s an electrolyte?

An electrolyte is a chemical that dissolves in water and also dissociates into ions. An aqueous solution of an electrolyte commonly conducts an electrical existing.

Instances of electrolytes include sodium chloride (NaCl), acetic acid (CH3COOH), sodium hydroxide (NaOH), sulfuric acid (H2SO4), and hydrochloric acid (HCl).

Typically, water soluble ionic compounds are electrolytes. They are electrolytes because ionic compounds consist of oppositely charged ions held together by an ionic bond. As an outcome, once these ionic compounds dissettle, their ions commonly gain the liberty to relocate around in solution.

What’s a non-electrolyte?

A nonelectrolyte is a chemical that dissolves in water without creating ions. An aqueous solution of a nonelectrolyte generally doesn’t conduct an electric current.

Instances of nonelectrolytes incorporate sugar (C12H22O11), ethanol (CH3CH2OH), and also acetone (CH3OCH3). Normally, water soluble molecular compounds are usually non-electrolytes. However before, we perform have actually exceptions. For instance, molecular compounds through the formula HX, where X deserve to be: Cl, Br, and I are polar covalent that disfix and dissociate in water.
