*Upon testing the pH of our standard solutions, it was observed that the pH was too low(~7.8). | |||
*To adjust the pH of the solution, 0.1mL of ionic strength adjuster (4M pH adjuster containing NaOH) was added to each of the 3mL solutions before testing. | |||
*The ionic strength pH adjuster adjusted the pH of the solutions to a new pH value between 8 and 10. | |||
