Question: Assuming that before pouring the white liquid from the upper container in the image, you first add a small spoonful of household baking soda (sodium bicarbonate) to the transparent liquid in the glass, what is most likely to happen?
A. The liquid will foam vigorously, possibly accompanied by a hissing sound.
B. The liquid’s temperature will drop significantly.
C. A chunky white precipitate similar to that in the image will form.
D. The liquid will turn light blue, similar to the effect of some acid–base indicators.
Clues:
1. The transparent liquid in the glass has many bubbles, indicating it is carbonated.
2. A green bottle with white branding, resembling a Sprite bottle, is visible in the background.
3. A white liquid, which looks like milk, is being poured into the glass.
4. Upon contact with the clear liquid, the white liquid is forming white, chunky clumps, which is characteristic of milk curdling in an acidic solution.
