if you have a mixture of sodium chloride and sodium bromide, could you use its conductance to determine the concentration of each solute ?explain

I am not sure of how to answer this question please some help!

To determine the concentration of sodium chloride (NaCl) and sodium bromide (NaBr) in a mixture, you can indeed use the conductance of the solution. Conductance is a measure of how easily an electric current passes through a solution. The ability of a solution to conduct electricity is determined by the presence of charged particles, called ions.

In the case of a mixture of NaCl and NaBr, both sodium chloride and sodium bromide dissociate into their respective ions in water. NaCl dissociates into sodium ions (Na+) and chloride ions (Cl-), while NaBr dissociates into sodium ions (Na+) and bromide ions (Br-).

When a direct electric current is passed through a solution, the ions in the solution move towards the oppositely charged electrodes (anode and cathode). The movement of ions creates an electric current.

The magnitude of the current passing through the conductive solution is directly related to the concentration of ions in the solution. In other words, a higher concentration of ions leads to a higher conductance.

To determine the concentration of each solute in the mixture, you can follow these steps:

1. Measure the conductance of the solution using a conductance meter. Ensure that the solution is sufficiently diluted and at a constant temperature to obtain accurate results.

2. Prepare separate solutions of known concentration using pure NaCl and NaBr salts.

3. Measure the conductance of the pure NaCl and NaBr solutions under the same conditions as the mixture.

4. Plot a calibration curve by relating the known concentrations of NaCl and NaBr with their respective conductances. This will provide a relationship between concentration and conductance for each salt.

5. Compare the conductance value of the mixture to the calibration curve and determine the corresponding concentrations of NaCl and NaBr.

Using the obtained concentrations, you can then calculate the molar ratio or mass ratio of NaCl to NaBr in the mixture.

It's important to note that this method assumes that the conductance of the solution is solely due to the ionization of NaCl and NaBr. Factors such as temperature, impurities, and other dissolved substances may affect the conductance, so controls and precautions must be taken into account when performing this analysis.
