Introduction
swimmers are frequently advised to leave the water after strikes of lightening. What is the scientific basis for this? What property of water makes swimmers corned when electricity is around? What other liquids possess the same property? Does distilled water behave the same?
Consider the following;
a. What takes place when a solute dissolves in a solvent? How would this be determined?
b. What process in the molecular level takes place to explain what is observed?
c. Do all solutes dissolve in the same way? Do acids and bases dissolve in the same way?
Solutions capable of conducting electricity, such as ionic compounds, are referred to as electrolytes. There are three major classifications …show more content…
Strong electrolytes disassociate completely, while weaker electrolytes only disassociate partially.
Electrolytes
Acids
Acids dissociate (or ionize) in water and produce hydronium ions. Strong acids dissociate completely while weaker acids ionize to a lesser degree.
Bases
Bases dissociate in water to produce hydroxide ions. Like in the case of acids, strong bases ionize completely, while weak bases only ionize partially.
Salts
Salts are different from acids and bases. They dissociate in aqueous solutions to produce a negative non-metal ion, and a positive metal ion. Soluble salts like the common table salt (NaCl) dissociates almost completely in aqueous solutions, while less soluble salts only disassociate partially (Schwarz, 2006).
Non-electrolytes
Some common non-electrolytes are table sugar (C12H22O11), and ethanol (CH3CH2OH).
Simple circuits can be constructed in the lab to test the conductivity of various solutions. The conductivity of these solutions can be determined using both qualitative and quantitative techniques. The conductivity of a solution is dependent on;
• Type of solute,
• Concentration of the solution, and
• The movement of ions in the …show more content…
The conductivity of each is represented by the brightness of the light. Brighter light indicates more conductive solution while less conductive solutions only produce dim light.
This table is used to clearly establish the conductivity of the different solutions; 0 for non-conductor- to 4 for excellent conductor.
