Volumetric Analysis

A solution of accurately known concentration is known as a

• standard solution

• known solution

• primary standard

• secondary standard

A solid substance of high purity and dryness is known as a

• pure standard

• desiccated standard

• primary standard

• secondary standard

Which of the following is not a primary standard?

• hydrochloric acid

• nitric acid

• sodium hydroxide

• none of these are primary standards

When a standard solution is prepared from a primary standard, the correct glassware to use is a:

• measuring cylinder

• volumetric flask

• Erlenmeyer flask

• beaker

In order to standardize a solution of hydrochloric acid you might accurately weigh some:

• anhydrous sodium carbonate

• hydrogen chloride gas

• oxalic acid crystals

• sodium hydroxide pellets

What is the name of the glassware shown?

• burette

• conical flask

• pipette

• Erlenmeyer flask

What is the name of the glassware shown?

• burette

• conical flask

• pipette

• Erlenmeyer flask

The burette should be rinsed with water followed by

• nothing

• water again

• the solution to be placed in the burette

• the solution to be placed in the conical flask

The pipette should be rinsed with water followed by:

• nothing

• water again

• the solution to be placed in the burette

• the solution to be placed in the pipette

The conical flask should be rinsed with water followed by:

• nothing

• the acid and then the base

• the solution to be placed in the burette

• the solution to be placed in the conical flask
