The task was to visualize acid. Even if a person does not know what this formula is, he should understand by looking at the model that it is acid. Colour combinations, associations..

To convey the texture of the acid, the chemical reaction —  I decided to use dots.

I also added a detail — an acid sign — to enhance the audience’s perception.

I made this from cardboard. I used acrylic paints. For the dots I used POSCA markers.
