Final answer:
AC is generally preferred for accuracy in measuring solute concentration due to its handling of impedance and reduced issues with electrode polarization, but DC can also be used for precision. Both AC and DC can be suitable depending on the method. Concentration is a quantitative measure of solute and solvent in a solution.
Step-by-step explanation:
The question pertains to the suitability of Alternating Current (AC) or Direct Current (DC) for measuring the concentration of a solute in a solution. Concentration is a quantitative measure of the relative amounts of solute and solvent present in a solution. For evaluating concentrations, molarity is a common unit, but there are other units of concentration used based on convenience or convention.
In the context of electrochemical measurements, AC is generally preferred over DC for accuracy because AC can better handle the impedance of the solution and avoid problems such as electrode polarization and electrolysis, which can affect the precision and accuracy of the measurements. However, DC might sometimes be used for its precision in certain types of measurements. Given that the current conducted by the solution is characteristic of 1:1 electrolytes, utilizing either AC or DC could be deemed suitable depending on the specific method and equipment used. Thus, option c from the given choices would be correct, indicating that both AC and DC are suitable methods for measuring concentration of solute.
