Glycine has the structure NH2CH2COOH. it can lose a proton from the carboxyl group and form chelate rings bonded through both the N and one of the O atoms. Draw structures for all possible isomers of tris(glycinato)cobalt(III).
An oil bath maintained at 50.5 oC loses heat to its surroundings at the rate of 4.68 kJ/min. Its temperature is maintained by an electrically heated coil with a resistance of 60 operated from a 110 V line.
The resulting solution is then titrated with 0.1041 M sodium hydroxide, and 12.39 mL of the sodium hydroxide solution are needed to reach a phenolphthalein end point.
