The Properties of Honey

For my chemistry blog, I chose to do honey. Honey is sweet, sticky and everyone knows what it is, but no one really knows what its like. People know that honey can make breakfast more fun and cleaning more messy, but what is it like outside of the culinary arts? 

Physical Properties

  1. Viscosity - Honey has a low viscosity. It is much thicker than water, but besides being sticky, it moves rather quickly.
  2. State - Honey is liquid at room temperature. (What a surprise)
  3. Transparency - Honey is transparent! Though it has a dark shade of color, it is not an opaque liquid.
  4. Color - Honey has a brownish-gold color.
  5. Density - Honey has a density of 1.4 kg/L.
Chemical Properties
  1. Heat - For my first experiment, I decided to test the effects of heat on honey. Below you should see a picture of me attempting to boil honey. notice the lighter colored, opaque, precipitate forming above the honey. When this precipitate formed, the remaining substance had a lower viscosity.   
  2. Flammability - I am sorry to report that honey is NOT flammable. Actually it is barely affected by fire. When I attempted to set honey a blaze, I was unsuccessful. The honey closest to the flame didn't even harden or brown like creme brulee. It just sat there. The most the flame did, was heated it up to have a lower viscosity.
  1. Acid - My next experiment tests the effects of acid on honey. To represent acid I used vinegar from my own kitchen. Yes, vinegar is acidic, but don't worry. You will not die the next time you have tuna. Below you should see a picture of the vinegar I poured into a bowl of honey. Notice how the vinegar is all grouped together. The honey showed no reaction to the vinegar, other than forming a two phased heterogeneous mixture.
  2. Alcohol - I then tested the effects of alcohol on honey and got results similar to that of acid. When I poured the rubbing alcohol into the bowl of honey, I expected some kind of chemical reaction to occur, but to my dismay all that happened was the alcohol resting on top of the honey. Below you shall see a picture of a two phased heterogenous mixture of alcohol and honey.
  3. Windex - For my big finale I decided to test the effects of windex on honey, assuming with so many chemicals in a substance, an interesting reaction was bound to occur. Well the windex certainly beat the alcohol, but I'd have to give the award to Heat for most interesting results. When the windex was poured into the honey, it seemed to makes its way through the honey, as if a crevice was forming. But the honey then closed itself back up, leaving a line as if a scar had formed. It was not as interesting as it sounds. 
(The pictures are arranged in order they are mentioned in the list above)


  1. Really cool experiment! I am curious- does honey boil? What is it's boiling temperature (if there is one). It's really cool that you figured out that honey isn't flammable, I never knew that! It's really interesting that the acid and alcohol had a similar effect on the honey. Could you figure out why? The pictures are pretty awesome, and you did a great job! (I can help you arrange the pictures later, if you want).

  2. Jessi! Wow you did a really fabulous job! The unique way you introduced your object was really creative and grabbed the audience's attention. The organzation of the physical and chemical was easy to read and very easy to follow. I loved how you set apart the actual property by bolding it. It really popped out at me and because I'm a visual learner I helped me to understand what I was looking at. The pictures are also a great way to aid your experiment. However, if it is possible, it would be great if you could figure out a way to put them within the text it is talking about. If not, it is just as good :) I really enjoyed reading your blog! It's really great and I look forward to checking back later on in the year for updates.

  3. Great job!! I thought the blog was really well organized and it was easy to read! I also thought the honey that you chose to experiment on was a very creative object to work with! On the chemical properties, I felt like you really did a fantastic job explaining why you had chosen to list them as chemical properties. I also liked how you mentioned the viscosity as one of the physical changes. I think you did an awesome job with this assignment!
