Homework Help: Chemistry: Van´t Hoff factor for baking soda

  1. Aug 26, 2008 #1
    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

    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 van´t hoff factor to be 2, and 1 respectively. However I fail to find the van´t hoff factor for baking soda, could somebody please provide me with this value?
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    What is a baking soda formula? How does it dissolve? Does it dissociate? Can you write reaction equation?
