Jika dianggap mengion sempurna (nilai i = nilai teoretis), tentukan titik didih dan titik beku larutan 11,7 gram undefined dalam 1 liter air.
begin mathsize 14px style left parenthesis K subscript b space air space equals space 0 comma 52 space degree C space m to the power of negative sign 1 end exponent space dan space K subscript f space air space equals space 1 comma 86 space degree C space m to the power of negative sign 1 end exponent right parenthesis end style 

  1. ... undefined 

  2. ... undefined 

Jawaban:

Faktor Van't Hoff larutan undefined


Error converting from MathML to accessible text. 


Titik didih larutan Na Cl:


begin mathsize 14px style space increment T subscript b double bond m middle dot K subscript b italic middle dot italic i T subscript b bond T subscript b degree equals m over italic M subscript r cross times 1000 over m subscript air cross times K subscript b cross times italic i T subscript b minus sign 100 equals fraction numerator 11 comma 7 over denominator 58 comma 5 end fraction cross times 1000 over 1000 cross times 0 comma 52 cross times 2 T subscript b minus sign 100 equals 0 comma 208 space space space space space space space space space space T subscript b equals 100 comma 208 space degree C end style 


Titik beku larutan undefined:


begin mathsize 14px style space space space space space increment T subscript f double bond m middle dot K subscript f italic middle dot italic i T subscript f degree minus sign T subscript f equals m over italic M subscript r cross times 1000 over m subscript air cross times K subscript f cross times italic i 0 minus sign T subscript f equals fraction numerator 11 comma 7 over denominator 58 comma 5 end fraction cross times 1000 over 1000 cross times 1 comma 86 cross times 2 0 minus sign T subscript f equals 0 comma 744 space space space space space space space space space space T subscript f equals minus sign 0 comma 744 space degree C end style 


Jadi, titik didih dan titik beku larutannya masing-masing adalah begin mathsize 14px style 100 comma 208 space degree C end style dan Error converting from MathML to accessible text..
