SampleChemistry· MCQ+4 / -1
'x' g of NaCl is added to water in a beaker with a lid. The temperature of the system is raised from 1°C to 25°C. Which out of the following plots is best suited for the change in the molarity (M) of the solution with respect to temperature? [Consider the solubility of NaCl remains unchanged over the temperature range]
Four option plots of molarity M versus temperature t; options are graphs.
  1. A.See option (1) in the figure (M vs t plot)
  2. B.See option (2) in the figure (M vs t plot)
  3. C.See option (3) in the figure (M vs t plot)
  4. D.See option (4) in the figure (M vs t plot)
