4 thoughts on “What concentrations of different substances lower the freezing point of water the most?”

  1. Hi Avery! You spoke very clearly and explained your ideas well. The video about solutes, solvents, and solutions was also really helpful. One wish I have for you is that it would be helpful to add a few key points to your slides. A question I have for you is what are some common solutes that I may find in my house that are most effective in lowering the freezing point of water. I’m also curious as to how you’re planning on executing your experiment next year. Great work on your presentation!

    1. Hey Simran, thank you so much for the feedback. I agree putting points on the slides might have been a good choice.
      Finding solutes around your house is a really simple task. Practically anything that can be dissolved in water is water soluble. The most common substances that come to mind would be table salt or sugar but other things like soap, or even coffee powder and various soluble liquids. My experiment next year will be using different concentrations of solutes to find the different freezing times they take.

  2. This is really cool Avery!
    I never really thought about this before. Now it all makes sense (that’s why water freezes faster than juice).
    Anyways, I was wondering, is there a sollute that when dissolved in a solvent actually increases the freezing point? or is that not possible?

  3. Hello Avery!

    This was actually a very informative presentation since this has been one of those questions that I have almost always wondered about. The graphs and videos really helped to make understanding it a lot easier and I’m really glad you did this.
    So here’s my question for you, is there a reason why salt is used instead of other solutes to melt ice?
