A student adds sodium hydroxide solution to an acid and measures the pH. The results are:
Volume of NaOH added: 0, 2, 4, 6, 8, 10 cm³
Measured pH: 2.0, 2.5, 3.0, 4.0, 5.5, 7.0
What is the total increase in pH from 0 cm³ to 10 cm³ of NaOH added?
Volume of NaOH added: 0, 2, 4, 6, 8, 10 cm³
Measured pH: 2.0, 2.5, 3.0, 4.0, 5.5, 7.0
