Elian is testing his hypothesis that the more ripe an orange is, the more Vitamin C it contains. He takes four oranges of varying degrees of ripeness and squeezes samples of juice from each one. He then measures the concentration of Vitamin C in each sample of orange juice. He systematically adds a measured amount of a chemical called a titrant into the orange juice, waiting for its color to change. When its color changes, he knows that the amount of Vitamin C present in the juice is equal to the amount of the titrant he has added, which he can calculate. What does Elian think is the independent variable in this experiment?
orange ripeness
amount of titrant
color of the solution
