In this lab, a hydrometer is used to measure the density of sugar solutions. What would happen if the same hydrometer was used to measure the density of alcohol solutions? Density of water 1.00 g/mL Density of alcohol 0.79 g/mL The hydrometer will sink lower as you increase the amount of alcohol in the solution, because the alcohol will increase the density of the solution. The hydrometer cannot be used to measure the density of alcohol solution: it can be used only for sugar solution The hydrometer will sink lower as you increase the amount of alcohol in the solution, because the alcohol will decrease the density of the solution. The hydrometer will float up higher as you increase the amount of alcohol in the solution, because the alcohol will decrease the density of the solution. The hydrometer will float up higher as you increase the amount of alcohol in the solution, because the alcohol will increase the density of the solution.
