Water Analysis: Dissolved Carbon Dioxide (CO2)

Web48. Carbon dioxide is more soluble in hot water than in cold water. A. true B. false. Correct option is B. False. Explanation: Carbon dioxide is less soluble as the temperature of the water increases. So Carbon dioxide is less soluble in hot water than in cold water. It is more soluble in cold water because CO2 is gas. 49. WebFill the mixing bottle to the 15 ml mark with the water sample. Proceed as in the low range test.
