Hi, I have another question. I have a calcite equilibrated seawater whose pH is 8. and O am adding NaOH in 3 different steps. After adding NaOH, 100uL NaOH --> 8.09, 500uL --> 8.37 and other 500uL --> pH is 8.58. However, phreeqc doesn't show any similar result. My graph starts from 7.91 and changes until 7.924.
