and I have to answer the question:
Why might your measured value of the freezing point of water not equal 0oC?

You could have read the temperature incorrectly.
The measuring device was defective.
Other tutors may have other suggestions.
I have an idea that the question was supposed to have you answer why the f.p. was lower than 0oC and the answer would have been that it was a NaNO3 solution; BUT, I don't know that there is a valid chemical reason for it being higher.
