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.Hi, I have another question. I have a calcite equilibrated seawater whose pH is 8. and O am adding NaOH in 3 different steps.

The Greeks ate fairly simple foods. They ate a lot of bread that they would dip in wine or olive oil. They also ate a lot of vegetables such as cucumbers, beans, cabbage, onions, and garlic. Figs, grapes, and apples were common fruits. They used honey to sweeten their foods and make desserts such as honey cakes.

Another option in PHREEQC in place of alkalinity is to enter total inorganic carbon (C or C (4)). This quantity would be measured by acidifying a sample and measuring the resulting CO2 in the sample. TDIC can be though of as CO2 (aq) + HCO3- + CO3-2. Finally, if you enter both Alkalinity and C (4), PHREEQC will calculate pH.
