Main Answer:
If 5 ml of water and 5 ml of glucose solution were used in each serial dilution instead of 9 ml of water and 1 ml of glucose solution, the concentrations of the resulting glucose solutions would be 10 times higher than the concentrations achieved with the original dilution method.
Step-by-step explanation:
In a serial dilution with a dilution factor of 10, the concentration of the solution decreases by a factor of 10 with each dilution step. The concentration is calculated using the formula C1V1 = C2V2, where C1 and V1 are the initial concentration and volume, and C2 and V2 are the final concentration and volume.
In the original experiment, the dilution factor was achieved by adding 9 ml of water (diluent) and 1 ml of the glucose solution (solute). If this process is altered to use 5 ml of water and 5 ml of glucose solution, the initial concentration becomes 10 times more concentrated.
The change in the dilution ratio directly impacts the concentration of the resulting solutions. By using equal volumes of water and glucose solution in each dilution step, the concentration is higher because a smaller volume of diluent is added, leading to a more concentrated solute. This adjustment is crucial for accurate experimental design and understanding the effects of different dilution factors on the concentration of solutions in serial dilution experiments.
