Also look at Henry's law which is of direct interest to the above topic.
@ Positron
Thank you for the info.
Why do you think ďThe actual balance between the two is based on CO2 partial pressures combined with everything else in the air (N, O, H ect).Ē , when the Daltonís law says gas behave independently and other gasses can be completely ignored. The pressures are independent of each other.

Thanks
