How to Extract a pH indicator from a vegetable (Red Cabbage) | Home Lab

Описание: Watch how red cabbage juice changes color when tested with sulfuric acid (H₂SO₄) and sodium hydroxide (NaOH).

This simple chemistry experiment shows how natural anthocyanin pigments work as a pH indicator. In acidic solution the juice turns red, while in basic solution it shifts to green.
I cooked this organic indicator by boiling red cabbage in distill water and then filtering it. it is perfect acid base indicator that can made at home as fun science activity.
Perfect for students, science lovers, and DIY chemistry projects! 🌿⚗️
