Nan experiment you are asked to react hydrochloric acid with sodium hydroxide. when measuring the volume of the reactants, which instrument would give the greatest precision?

100 ml graduated cylinder
250 ml erlenmeyer flask
100 ml beaker
200 ml beaker

The correct option is, 100 ml Graduated cylinder.

Explanation:Graduated cylinder : It is measuring cylinder that is used to measure the volume of a liquid. It has a narrow cylindrical shape. The marked line drawn on the graduated cylinder shows the amount of liquid that has been measured.

Erlenmeyer flask : It is also called as a conical flask or titration flask. It is a laboratory flask that has flat bottom, a conical body and a cylindrical neck. It is commonly used for the titration.

Beaker : It is a type of laboratory equipment that has cylindrical shape and it is used for the mixing, stirring, and heating of chemicals.

As per question, the graduated cylinders are more accurate and precise than Erlenmeyer flasks and beakers.

100ml of graduated cylinder since it's easier measured that's reduce parallax error chance also it's small limit of precision

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
