Estimating Specific Conductance of Sulfuric Acid Solution
How can we estimate the specific conductance of a 0.0003M solution of sulfuric acid?
Given the specific conductance values for different concentrations of hydrochloric acid, what can we infer about the specific conductance of sulfuric acid in comparison?
Estimation of Specific Conductance of Sulfuric Acid Solution
When estimating the specific conductance of a 0.0003M solution of sulfuric acid, it is important to consider the nature of sulfuric acid as a diprotic acid.
While direct equivalence to the specific conductance of hydrochloric acid (HCl) may not be feasible due to differences in ionization, a rough estimate based on the given values can be made.
Specific conductance is a measure of a solution's ability to conduct electricity, influenced by the presence of ions in the solution. In the case of sulfuric acid (H2SO4), it is a diprotic acid, meaning it can donate two protons in solution compared to HCl, which is a monoprotic acid.
By referring to the specific conductance values provided for various concentrations of HCl (7,728 for 0.0200M, 1,892 for 0.0050M, 495 for 0.0013M, and 173 for 0.0003M), we can see a trend of decreasing specific conductance with lower concentrations.
Estimating the specific conductance of a 0.0003M solution of sulfuric acid based on the reference value for HCl, we can expect the value for H2SO4 to be slightly lower than 173 due to the incomplete second ionization of sulfuric acid.
It is important to note that the actual specific conductance of sulfuric acid may vary based on factors such as the degree of ionization and specific conductance of resulting ions.
