D-glucose এর কাজ, ব্যবহারের নিয়ম

If a solution is described by 10% glucose in water by mass, it means that 10 g of glucose is dissolved in 90 g of water resulting in a 100...

ΔG0 = – RT lnKc  ΔG0 = – 8.314 × 300 × ln( 2×1013 )  ΔG0 = – 7.64 ×104 J/mol.

Molecular mass of sulphur molecules (S8)  = 32 × 8 = 256 gm  Molecular mass of glucose (C6H12O6)  =(6 × 12) +( 1 × 12) +( 6 × 16)  = 72 + 12 +...

Molecular mass of glucose (C6H12O6) = 6 × 12 + 1 × 12 + 6 × 16 = 72 + 12 + 96 = 180 g  %of carbon(C) in glucose =...

Mass of glucose, w =36 g Osmotic pressure, π = 4.98 bar Temperature, T = 300 K Volume of solution, V = 1L The formula of osmotic pressure= Π = CRT n/vRT Plug the value and solve for R we get R =...

[Hint :  (a) (b) NaNO3 + H2SO4 =>NaHSO4 + HNO3]

(1) Aldehydes give 2, 4-DNP test, Schiff’s test, and react with NaHSO4 to form the hydrogen sulphite addition product. However, glucose does not undergo these reactions. (2) The pentaacetate of glucose...

A glucose molecule contains five −OH groups while a sucrose molecule contains eight −OH groups. Thus, glucose and sucrose undergo extensive H-bonding with water. Hence, these are soluble in water. But...

HCl, HNO3, etc., ionise in the aqueous solution to produce H+ ions. Hence, they show acidic character. Compounds like C2H5OH and glucose do not ionise in the aqueous solution to give...
