The child under observation is Lilly who is a baby girl aged 2 years and born in November 2019. All fatty acids have a "fatty" part (the hydrocarbon tail) and an "acid" part (the carboxylic acid head). Saponification occurs when a fat is heated with a strong base such as sodium hydroxide (NaOH) to give glycerol and the sodium salts of the fatty acids, which is soap. minDate: new Date(d.getFullYear(), 1-1, 1), The observation is taken b Antigone and Socrates had different attitudes towards the law. Add 5 ml oflaboratorywater into the first tube, add 5 ml of the soap solution into the second test tube, and add 5 ml of the detergent solution into the last test tube. It is important to have at least 100.0 g, but it is ok if you weigh out slightly more than this amount. Add a magnetic stir bar to the beaker. 1.
