Hydrochloric acid and sulphuric acid are the strong acids that completely dissociates in the aqueous solution. Since the solution contains more ions which move freely in the solution and help in passing electricity, hence we can say Hydrochloric acid and sulphuric acid are the best conductors of electricity.
How do you determine the best conductor of electricity?
Explanation: One way to assess conductivity, is to look up resistivity , which is a physical property of the substance that shows it tendency to resist the flow of electricity. The lowest resistivity among the metals is that of silver, followed by copper and then gold.
How can you tell which solution has the greatest electrical conductivity?
Compounds with Strong Conductivity
The higher the concentration of ions, the greater the conductivity. Table salt, or sodium chloride, is an example of a compound with strong conductivity.
How do you know if a solution conducts electricity?
1 Answer
- If electrons can move around freely (as in the delocalized bonds of metals), then electricity can be conducted.
- If ions can move around freely, electricity can be conducted.
How do you know if a solution is conductive?
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.
Which of the following solution has the highest electrical conductivity?
Fluoro group causes negative inductive effect increasing ionisation, thus 0.1 M difluoroacetic acid has highest electrical conductivity.
Which of the following solutions have highest conductivity?
HCl is strong electrolyte and one of its ion is which has highest movability due to jumping mechanism.
How do you know if something is a conductor or insulator?
Touch the open ends of the two wires to each other to form a circuit and test the bulb. Touch the two open ends of the wire to each material you are testing, one at a time. If the bulb lights up, it is a good conductor. If it doesn’t, it is a good insulator.
Why are some solutions better conductors of electricity?
Strong acids and bases are usually strong electrolytes. … In other words, strong electrolytes have a better tendency to supply ions to the aqueous solution than weak electrolytes, and therefore strong electrolytes create an aqueous solution that is a better conductor of electricity.
Which of the following will conduct electricity the best?
What Metal is the Best Conductor of Electricity?
- Silver. The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity. …
- Copper. One of the most commonly used metals to conduct electricity is copper. …
- Aluminum.
What makes a solution conductive?
Conductivity in aqueous solutions, is a measure of the ability of water to conduct an electric current. The more ions there are in the solution, the higher its conductivity. Also the more ions there are in solution, the stronger the electrolyte.
What determines electrical conductivity?
The electrical conductivity of a metal (or its reciprocal, electrical resistivity) is determined by the ease of movement of electrons past the atoms under the influence of an electric field.
Why are metals good conductors?
Metals are good conductors (both of heat and electricity) because at least one electron per atom is free: i.e., it is not tied to any particular atom, but is, instead, able to move freely throughout the metal.
What type of compound conducts electricity in solution?
Substances whose solutions conduct electricity are called electrolytes. All soluble ionic compounds are strong electrolytes. They conduct very well because they provide a plentiful supply of ions in solution.
