Hello,
Im writing up a lab involving boiling point elevation of distilled water when solutes are added to it and im using the equation:
deltaT = iKm
where:
deltaT is the change in boiling point of the solvent,
K is the molal boiling point elevation constant, and
m is the molal concentration of the solute in the solution.
I calculated the predicted elevation for salt and sugar, which i could find their vanīt hoff factor to be 2, and 1 respectively. However I fail to find the vanīt hoff factor for baking soda, could somebody please provide me with this value?
Thanks
