Question

Are there ions that dissociate from glucose when it is dissolved in water? How might that influence the conductivity observed? a. What happens to the theoretical pH of the solution as you dilute it 10-fold each time?

Answer 1

• Glucose dissolves in water by making hydrogen bonds with water molecules.
• That is glucose doesn't dissociate into ions in water.
• It is considered a non electrolyte.Therefore solution containing glucose do not conduct electricity.
• Glucose doesn't contain any basic or acidic functional groups.So it is chemically neutral in nature.
• In other words, glucose can't alter the pH level of a solution and therefore glucose solution have a pH value same as the pH of water.
• So when we dilute glucose solution,it will not make any difference in theoretical value of pH.
