You need to use a dilute hydrochloric acid solution in an experiment. However, the only bottle of hydrochloric acid in your lab’s acid‑base cabinet is 8.0 M. Calculate the pH of the solution you prepare by diluting 1.5 mL of the 8.0 M HCl to a final volume of 250 mL with H2O. Use appropriate significant figures in your answer.

The reaction q+r2=r2q is found to be first order in r2 and
