Molar conductivity ( ⋀ _ m ) of aqueous solution of sodium...

Molar conductivity (⋀m)\left({⋀}_{m}\right) of aqueous solution of sodium stearate, which behaves as a strong electrolyte, is recorded at varying concentration(c) of sodium stearate. Which one of the following plots provides the correct representation of micelle formation in the solution?
(Critical micelle concentration (CMC) is marked with an arrow in the figures.)Molar conductivity ( ⋀ _ m ) of aqueous solution of sodium stearate, which behaves as a strong electrolyte, is recordedMolar conductivity ( ⋀ _ m ) of aqueous solution of sodium stearate, which behaves as a strong electrolyte, is recordedMolar conductivity ( ⋀ _ m ) of aqueous solution of sodium stearate, which behaves as a strong electrolyte, is recordedMolar conductivity ( ⋀ _ m ) of aqueous solution of sodium stearate, which behaves as a strong electrolyte, is recorded

Options

  1. AWhat aspect of controlling the sweetness of food is challenging when using alitame?
  2. BWhat aspect of controlling the sweetness of food is challenging when using alitame?
  3. CWhat aspect of controlling the sweetness of food is challenging when using alitame?
  4. DWhat aspect of controlling the sweetness of food is challenging when using alitame?

Correct answer

C. What aspect of controlling the sweetness of food is challenging when using alitame?

Step-by-step solution

With increase in concentration of sodium stearate \lambdaM{\text{\lambda}}_{\text{M}} decreases, but at CNC, formation of miceller take place and the \lambdaM{\text{\lambda}}_{\text{M}} decrease abruptly, this change in \lambdaM{\text{\lambda}}_{\text{M}} with respect to c\sqrt{\text{c}} is represented by plot.
