The lowest electrical conductivity has the fewest ions… C2H5OH. All other substances above form ions in solution.
Which of the below solution best conducts electricity?
Explanation: Because, NaOH is strong base, which completely dissociate and gives Na+ and OH- ions, which helps in conducting electricity and among above 4 options, 0.1M NaOH is strong so, it is best solution for conduction of electricity.
What is the conductivity of NaOH?
Specific conductivity of 0,1 M NaOH aqueous solution amounts to 0,0221 S·cm–1. After addition of the same volume of 0,1 M HCl aqueous solution, the specific conductivity falls down to 0,0056 S·cm–1, while after addition of the second equal aliquot of the same HCl solution, its value increases to 0,0170 S·cm–1.
What makes a solution more conductive?
There are three main factors that affect the conductivity of a solution: the concentrations of ions, the type of ions, and the temperature of the solution. 1) The concentration of dissolved ions. An electrolyte consists of dissolved ions (such as Na+ and Cl-) that carry electrical charges and can move through water.
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 solution is the most effective to conduct electricity for the brightest light?
Sodium chloride is a soluble salt that is known as a strong electrolyte, as it creates a concentrated solution of electrically charged ions. The solutions of sodium hydroxide, a strong base, and sulfuric acid, a strong acid, complete the circuit, allowing the bulb to glow brightly.
Can C6H12O6 conduct electricity?
Copper conducts electricity, while sugar, C6H12O6, does not.
Is MgSO4 a good conductor of electricity?
Going further, both MgSO4 and K2SO4 are ionic compounds. They consist of a metal Mg (magnesium) and a polyatomic ion (sulfate) as well as potassium metal and sulfate ion. Both of these compounds can conduct electricity.
Can Hcooh conduct electricity?
YES! formic-acid (HCOOH) in water dissolves into ions (H+ and COOH-). … and to conduct electricity a solution must have ions. so formic acid is a weak electrolyte (compared to water, for example).
Is NaOH a weak base?
Because HC2H3O2 is a weak acid. Any chance a weak acid has to form, it will (the same with a weak base). As some C2H3O2− ions hydrolyze with H2O to make the molecular weak acid, OH− ions are produced. OH− ions make solutions basic.
12.5: Strong and Weak Acids and Bases and their Salts.
Is Cl or OH a better conductor?
are 76 for Cl and 198 for OH- in units of ohm^-1 cm^2. Thus the NaOH is more conducting. Because the chloride ion has a greater mass than the OH- ion, we can see without calculation that for solutions of equal mass (e.g. 10 g/l) then the NaCl would contain fewer ions, thus would be further disadvantaged.
