Why isn't sucrose an electrolyte? How could you make 3 L of a 0.2 M solution of glucose (C6H12O6)? Why is it unwise to boil the oxalate solution in preparation for its titration with permanganate? Please explain briefly. Why is it important to add the sulfuric acid drop-wise to the et...
Why does HCl dissociate faster than ether? Why is O_2 nonpolar? Why can't benzene dissolve sodium chloride? Briefly explain how the conduction of electricity takes place in iron metal. Why does the Br ion attach to the carbon with the CH3 group and not to the carbon to the left of it...
A conductivity cell is used to measure the conductance of electrolyte . It makes use of conductivity of water which does not contain any ions. The cell constant of conductivity cell is determined. Calculate α of CH3COOH if Δ∞.m for HCl,NaCl,CH3COOHNa are 426,126,91Scm2mol−1, respe...
Arrhenius theory: Arrhenius theory isapplicable to aqueous solutions and not to non-aqueous solutions and gaseous solutions, as it defines electrolyte in terms of aqueous solution and not as a substance. The role of solvent is not responsible for deciding the nature of strength of an electrolyte....
Why is it necessary to remove water from an acetal reaction? Why is the solubility of butane 6.1 mg / 100 g water, yet hexane is immiscible in water? Why is MgF_2 polar? Why is pure water neutral? Why water is a weak electrolyte?
Why is it necessary to remove water from an acetal reaction? Why should water be avoided from cyclopentadiene which is dried by distillation? Explain using equation. Why water is a weak electrolyte? Why is it important to dry the organic layer before distillation?
Is sodium chloride classified as an element, a compound, or a mixture? Explain. Why do the chemically similar alkali metal chlorides NaCl and CsCl have different structures, whereas the chemically different NaCl and MnS have the same structure? Why does HCl dissociate faster than ether? Does sol...
Explain why some electrolyte solutions are strongly conducting, whereas others are weakly conducting. How does galvanizing prevent corrosion? Give an example. Why is barium more reactive than magnesium? Define the term cathode. Why do metallic compounds conduct electricity a...
The compound zinc sulfate is a strong electrolyte. Write the reaction when solid zinc sulfate is put into water. A substance has a low melting point. It does not conduct electricity either when melted or as a solid. It is most likely: A. Diamond (C) B. Copper (Cu...
