A hydrometer or a refractometer can be used to measure the salinity level of a saline solution. These tools are specifically designed to measure the concentration of dissolved salts in a liquid.
The scientist should use a pH meter to measure the precise pH of the solution. This device provides an accurate numerical value for the acidity or alkalinity of the solution.
A burette is a common tool used to measure liquids accurately in chemistry experiments, including acids. Burettes allow for precise control of adding acid to a solution, making them a reliable tool for measuring acid volumes. However, the choice of the "best" tool ultimately depends on the specific requirements of the experiment and the level of accuracy needed.
To make slime, you will need glue, water, baking soda, saline solution, and optional food coloring. Mix the glue with water, add baking soda, and then slowly incorporate saline solution until the desired slime consistency is reached. Feel free to customize with glitter or beads for added fun!
A graduated cylinder or a pipette would be the best tools to measure 50ml of alcohol precisely. These tools are designed for accurate volume measurement and are common in laboratory settings.
You should use a pH meter or pH paper to measure the acidity of a solution. These tools provide a way to quantitatively determine the concentration of hydrogen ions in the solution, which correlates with its acidity.

You would use a thermometer to measure air temperature.
depends on what item you are measuring
A cloth tape measure.
A tape measure would be the tool, measuring in centimetres or inches.
The tool that a person would use to measure out a pound is called a scale. A scale can be used to weigh people as well. Pounds are a form of measure used on the Imperial system.
A balance.
Micrometer
a tape measure
Is this a riddle?
well the tool would use a triple beam balance because it has more mass.
A balance is the best tool for measuring mass.
