Structure and properties Index of refraction, n D: 1.000449 at 589.3 nm and 0 °C [1]: Dielectric constant, ε r: 1.60 ε 0 at 0 °C, 50 atm : Average energy per C=O bond : 804.4 kJ/mol at 298 K (25 °C) [2]
This measurement of the amount of carbon dioxide lost is an excellent estimate for total carbon dioxide production. Once this is known, the total metabolic rate may be estimated from simplifying assumptions regarding the ratio of oxygen used in metabolism (and therefore heat generated), to carbon dioxide eliminated (see respiratory quotient ...
The indicator is used in photosynthesis and respiration experiments to find out whether carbon dioxide is being liberated. [1] It is also used to test the carbon dioxide content during gaseous exchange of organisms. When the carbon dioxide content is higher than 0.04%, the initial red colour changes to yellow as the pH becomes more acidic.
