Answer:
Prepare solutions of different acid concentrations, measure 50 milliliters of each into different beakers, and place the same type of medication of the same mass into the beaker
Step-by-step explanation:
The experiment to test the effect of stomach acid concentration on the solubility of a particular oral medication will have the following configuration;
The independent variable = The concentration of the acid to which the medication is added
The dependent variable = The solubility of the medication in the acid concentration
The constant = The medication which is added to the acid concentration
The controls = The fixed mass and type of the particular medication and fixed volume of the different concentrations of the acid samples.
