3. Estimate the carbon dioxide content of a natural water sample in mg/L which has a pH of 7.5 and a bicarbonate-ion concentration (as HCO3) of 50 mg/L. Assume that the effect of the dissolved solids on ion activity is negligible and the water temperature is 25°C. Hint: KA for carbonic acid (H₂CO3) at 25 °C is 4.3 x 10-¹7.
