A 220 mL sample of a 0.500 M NaCl solution with an initial pH of 7.00 is subjected to electrolysis. After 18 minutes, a 10.0-ml portion (or aliquot) of the solution was removed from the cell and titrated with 0.100 M HCl solution. The endpoint in the titration was reached upon addition of 22.8 mL of HCL. Part A Assuming constant current, what was the current (in A) running through the cell? Express your answer to two significant figures and include the appropriate units. PA ? IM Value Units
