Simple chemical experiment

1. Nature Explorers Club
WE RECOGNIZE ACIDS AND BASES
USING RED CABBAGE STOCK

2. BOIL RED CABBAGE WITHOUT SALT

3. WE NEED VINEGAR AND BAKING SODA

4. INTO THE GLASS ON THE RIGHT WE POUR VINEGAR
(ACID), ON THE LEFT – WE ADD BAKING SODA (BASE)

5. THE STOCK CHANGES ITS COLOUR: BAKING
SODA (BASE) IS BLUE, VINEGAR (ACID) IS RED

6. WE TOOK TWO PLATES. ON THE PLATE ON THE LEFT WE
POURED SOME VINEGAR, AND ON THE PLATE ON THE
RIGHT WE POURED SOME WATER WITH BAKING SODA

7. WE CAN SEE THE RESULTS AGAIN: ROLLED PIECES OF PAPER
TOWEL ARE RED-PURPLE ON THE PLATE WITH VINEGAR (ACID)
AND BLUE – ON THE PLATE WITH BAKING SODA ( BASE)

8. WHEN WE POUR THE STOCK WITH BAKING
SODA INTO THE STOCK WITH VINEGAR WE GET
PURPLE VOLCANO

9. SCIENCE IS FUN!!!

10. POLISH EXPLORERS HAD FUN MAKING THIS
EXPERIMENT 

11. THANK YOU FOR WATCHING 
