Consider the Solubility Curve for this Problem: Analysis for KClO3 & NH4Cl

MW (KClO3) =  122.55 g/mol   ,   MW (NH4Cl) =  53.49 g/mol

i) What is the temperature at which KClO3  & NH4Cl both have the same solubility?  Round to nearest degree. +/- 1°
  T =  °C

 

ii) What is the solubility (g per 100g H2O) at this temperature.  Round to nearest gram.  +/- 1 g

  s (KClO3) =     g/100g H2O

  s (NH4Cl) =     g/100g H2O

 

iii) What is the molar solubility for KClO3 at this temperature?  Assume the density of the solution is 1.21 g/cc.  Round off to 2 sig. figs.

  |s| KClO3 =       M

iv) Calculate the Ksp for each of these chemicals at this temperature.

   Ksp = 

 

v)  What is the unit of Ksp for KClO3?

  Unit for Ksp =
