conclusions: how is the difference in the physical properties of the powdered mixture components being used to separate them in
Advocard [28]
  • Sedimentation and Decantation is the process of setting of solid particles from a liquid either to produce a concentrated slurry or to clarify a liquid containing solid particles . The solid must not be mixed with liquid. For example- sand insoluble in water
  • Sublimation -  In this process solid phase is directly transformed  into vapour form without passing through liquid phase.This method is used in the purification of those substances which have sublimation property. At first the mixture should be sublimed before dissolution in liquid.
  • EX- Iodine , naphthalene, ammonium chloride etc. Here, NH4Cl is seperated by sublimation.
  • Evaporation is a technique used to separate out homogeneous mixtures where there is one or more dissolved salts. The process convert  the liquid components from the solid components. The process typically involves heating the mixture until no more liquid remains.
  • so, now by evaporation of the liquid solvent we finally get the salt that was dissolved in it that is NaCl.

A 10.1 g sample of NaOH is dissolved in 250.0 g of water in a coffee-cup calorimeter. The temperature increases from 23.0 °C to
givi [52]

Hey there!:

moles of NaOH = 10.1 / 40 = 0.2525

heat  = ΔH   x  moles

= 44.4 x 0.2525

= 11.21 kJ

total mass  = 10.1 + 250 = 260.1 g

Q  = m Cp dT

11211    = 260.1 x  4.18 x dT

dT  = 10.3

T2  = 10.3 + 23  = 33.3 °C

temperature = 33.3 ºC°

Hope this helps!
