Tough question about solubility.

I don't think I could solve this back when I was good at it.

 

What would be expected to precipitate from water saturated in carbon dioxide, calcium carbonate and gypsum including a substantial amount of sodium decahydrate and some sodium bicarbonate and sodium chloride as the pressure decreases and the temperature increases? There are several more exotic compouns in trace quantities.

 

I suppose the question really boils down to what is the proportion of gypsum to calciuum carbonate in carbonic acid?

 

Thanks very much in advance for any help.

One last try here.

 

The CO2 would be dissolved first and under extremely high pressure around 54 degrees F. Assume ample quantities of gypsum and calcium carbonate for saturation.

 

I don't need exact numbers so much as a ballpark estimate of the proportions.
