1. In a seawater aquarium (1 atm) at 35 psu, 24˚C and a pH of 8.1, you measure a carbonate (CO32-) concentration of 24 µmol/kg. (a) What are the concentrations of HCO3- and H2CO3?

(b) Is the solution saturated with respect to CaCO3 ? What is the % saturation?

(c) If you were to add CaCO3 to reach saturation, how much would you need to add?

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
