The value of the constant \(A\) in the Debye - Huckel -Onsager equation, \(\lambda_{ m }=\) \(\lambda_{m}^{0}-A \sqrt{C}\) depends on temperature, charges of the ions, the dielectric constant of the solvent and also the viscosity of the solvent. Here, since we are not given the solvent, we will assume that the solvent is the same for each case. Here, the deciding factor is the charge on the ions. Again, in \(NH _{4} Cl\) and \(NaBr\), the charges on the ions are the same.
Hence the pair of electrolytes that will possess the same value for the constant (A) will be \(NH _{4} Cl , NaBr\).
Electrolysis of 600 mL aqueous solution of NaCl for 5 min changes the pH of the solution to 12. The current in Amperes used for the given electrolysis is ….. (Nearest integer).
Electrolysis is the process by which an element is decomposed and undergoes some chemical change under the influence of any electric current. The first-ever electrolysis was executed out by Sir Humphrey Davey in the year 1808. Electrolysis can occur in both Galvanic cells and Electrolytic cells.
