• Concentration

• Density

• Solubility

Choose the correct definition of a primary standard solution/reference standard solution

• substances that are stable chemical compounds and available in high purity

• substances that are stable chemical compounds and contain high moisture

• substances that are volatile chemical compounds and available in high purity

• substances that are volatile chemical compounds and available in high moisture

Working standard or secondary standard solution are substances with concentration or purity that has been determined analytically using _______________

• primary standard

• reference standard

• all of the options

The following are the characteristics of primary standards EXCEPT

• Not hygroscopic

• High purity

• High stability

Choose the correct definition for molarity, M

• the number of moles of solute per liter of solution

• the number of moles of solute per kilogram of solution

• the number of particles of solute per liter of solution

Choose the correct definition for molality, m
