Measure the rate of yeast fermentation. Tube 4) will have the tallest height, indication the most CO2 formation.
Tinkering with yeast and sugar concentrations allows for a multitude of varying alcohols and breads to contribute to the worlds current stock of recipes. Lavoisier found that when he added the sugar to the reaction two-thirds of the sugar ended up producing alcohol and the other third was oxidized and became waste in the form of CO2 (This is why there is foam produced on top of most beers). Therefore with a greater mass of sucrose, it results in longer amount of time in which CO2 is being released, in which pH also drops.

The usefulness of fermentation as a means of deriving energy is limited because. Earliest humans were foragers who col lected and ate leaves, tubers, fruits, berries, nuts, and cereal seeds most of the day much as apes do today in the wild. Yeast fermentation has been used commercially since the 18th century to brew alcohol, when French chemist Antoine Lavoisier found that in an experiment when he added sugar to the reaction.
