what does addition of potassium nitrate to ice results in??why and how?
a)increase in melting point
b)decrease in melting point
c)change in colour of ice
d)both (a) &(b)
(please give the answer with explaination)
Option B is the correction answer because depression in freezing point depends upon the number of atom, ion or molecules present in the solution which decreases the polarity between solvent molecules. For example: Addition of NaCl to water decreases its freezing point to -9 ° C i.e. at this temperature water will melt also.
