What is the difference between the conductivity of ionic and covalent compounds?
Although solid ionic compounds do not conduct electricity because there are no free mobile ions or electrons, ionic compounds dissolved in water make an electrically conductive solution. In contrast, covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.
How do you find the conductivity of a compound?
To calculate the conductivity of a solution you simply multiply the concentration of each ion in solution by its molar conductivity and charge then add these values for all ions in solution.
How do you classify compounds based on conductivity?
If a compound cannot conduct electricity in its solid or liquid state, it is covalent. If a compound does conduct electricity when dissolved in solution or molten, it is an ionic compound.
Why do ionic compounds have different conductivity values?
Compounds with strong conductivity dissociate completely into charged atoms or molecules, or ions, when dissolved in water. The higher the concentration of ions, the greater the conductivity.
What is the relationship between conductivity and concentration?
Answer: Specific Conductivity decreases with a decrease in concentration. Since the number of ions per unit volume that carry current in a solution decrease on dilution. Hence, concentration and conductivity are directly proportional to each other.
What does it mean if a compound is conductive?
Compounds with strong conductivity dissociate completely into charged atoms or molecules, or ions, when dissolved in water. These ions can move and carry a current effectively. The higher the concentration of ions, the greater the conductivity.
How do you measure conductivity of water?
By touching the negative and positive leads of a multimeter that is on in the resistance setting allows you to measure the conductivity of water, a test of its purity. When water conducts electricity, it is made possible by water impurities such as metals. The standard unit of measure for conductivity is microsiemens per centimeter.
What causes high conductivity in water?
How to Treat High Conductivity in Water. Conductivity is the result of the presence of mineral salts of elements like sodium, calcium and magnesium. These salts when dissolved in water, produce free ions that are capable of passing electrical current in water. High conductivity is related to high TDS (total dissolved solids) concentration in water,…
How does conductivity affect water quality?
Conductivity At present there is no water quality index associated with conductivity, although some values may be better than others for a particular body of water. Conductivity can be used as a measure of total dissolved solids (TDS).
What does high conductivity in water mean?
These salts when dissolved in water, produce free ions that are capable of passing electrical current in water. High conductivity is related to high TDS (total dissolved solids) concentration in water, amount of dissolved mineral salts in water.
