You are given a 5 mM solution of sucrose. If you hydrolyse it by adding equal volume of 10 mM HCl, what would be the final concentration of glucose and fructose in the hydrolysate?
Select an option to attempt
Correct Answer: Option B
Explanation
Sucrose hydrolysis and dilution:Step 1 — Dilution: 5 mM sucrose + equal volume of 10 mM HCl → total volume doubled → sucrose concentration halved:Step 2 — Hydrolysis: Sucrose → Glucose + Fructose (one-to-one stoichiometry)2.5 mM sucrose → 2.5 mM glucose + 2.5 mM fructose.Note: HCl acts as a catalyst for hydrolysis; it does not affect the stoichiometry. Answer: 2.5 mM glucose and 2.5 mM fructose (Option 2).
