Reaction 25.1 Sucrose (aq) + H2O (l) ⇄ Glucose (aq) + Fructose (aq)
What is the Keq expression for Reaction 25.1?
C6H8O6(aq) + C12H7O2NCL2(aq) ----> C6H6O6(aq) + C12H9O2NCL2(aq)
- C12H7O2NCL2 is abbreviated as DCIP
- Molar Lass of C6H8O6(s) is 176.14 g/mol
- Daily recommended intake (DRI) for adults: 90 mg of Vitamin C
Askor & Bich found that it required 23.14 mlof 1.32 x 10^-3 M DCIP soliution to reach the endpoint when titrating a 7.50ml aliquot of pear juice.
How many mg of ascorbic acid, C6H8O6 are present in the juice aliquot? _5.38_____(can you please show how to calculate this answer)
