Mucic Acid Test Quiz

What is the primary purpose of the Mucic Acid Test?

• To measure the pH of a solution

• To detect the presence of glucose

• To identify proteins in a sample

• To detect the presence of galactose

What is the chemical formula of mucic acid?

• C6H10O8

Which gas is produced as a side product during the Mucic Acid Test?

• Nitrogen dioxide

• Oxygen

• Carbon dioxide

• Hydrogen

Why is the Mucic Acid Test considered specific for galactose?

• Because it changes color with galactose

• Because it forms an insoluble precipitate with galactose

• Because it forms a soluble compound with galactose

• Because it reacts with all sugars

What is a limitation of the Mucic Acid Test?

• To cool the solution

• To evaporate the solution to about 1 ml

• To dissolve the crystals

What indicates a positive result in the Mucic Acid Test?

• Formation of a colored solution

• Emission of a sweet smell

• Formation of insoluble white crystals

• Change in pH

Which test tube in the experiment showed a negative result?

• Tube 1

• Tube 2

• Tube 3

• Tube 4

What does the absence of insoluble crystals indicate in the Mucic Acid Test?
