WARNING: This experiment uses corrosive materials. Use protective gloves.
Jon Chase creates his own acidity indicator and then tests a series of household products.

You need:
Red Cabbage
Water
Knife/ Blender
Ice Cube trays
Household ingredients
Sieve
Jug
Six clear glasses
Rubber gloves
Instructions:
Chop up cabbage
Put cabbage in blender with some water
Strain solution into a bowl using the jug
Pour your household ingredients in to the glasses
Leave one glass empty
Add the cabbage solution

how long will that cabbage juice store for? what's the best way to store it? the refrigerator? freezer? thanks
Huh, I've noticed before that whenever I make a batch of Kimchi out of red cabbage it gradually changes color from dark muddy purple to florescent pink over the course of a week as it ferments and sours. Now I know why!
Why does alkaline/base share two names, whereas acid is just acid?
is vineget a good ph down solution for plants?
I like your experiment and also how to speak.
Very interesting! just one thing… 0 to 14… not 1 to 14
where and how did the shirt change ?
Thanks. My homework in chemistry is now DONE! :))
If you mixed any of those acid with the base, would the reaction be the same? I'm thinking of trying it
its not live anymore lol
Btw it smells like ass so open the windows up.
You'd think that BBC has way better equipment than a simple tripod.
Good experiment, and good explanation. I would however want him to stress the fact that you never put the water into the acid. It is always the other way around, since otherwise, the reaction can be very exothermic and start to boil and splashing acid around. It is good to reinforce these points early so they are in the back of peoples minds when they start to experiment with more concentrated solutions or heavier stuff.
Peace!
His shirt didn't change; the entire set was reversed.
i was making a joke referring to lsd haha :P
This guy is awesome
Me too.
I think there is still some acid rattling round inside me.
How is it misleading? He's showing how to test the acidity with a "home made" PH indicator. The title is exactly what the video was about.
Awesome stuff!
agreed, I like the the shaky style, brings life to the video
He's not "gangsta", I agree, but he's almost certainly from a West Indies (Caribbean) background. Lots of people from those places moved to the UK in the 70s, and they have a distinct accent which sounds a lot like "gangsta" accent, but is distinct from it.
Well, maybe "gangsta" culture is trying to imitate Caribbean accent, I don't know. At any rate, it doesn't concern Jon.
Indeed :/
Either that or i am a very bad person…
misleading title..
His t-shirt didn't change you just mirrored the video
lol looks like you don't chop up cabbage very often..
I felt like this was an explanation of the pH scale for dummies. The only new thing I learned was red cabbage has a natural indicator of pH..nevertheless, good job on the video
4:12 lmao
Potentially the most patronising video I've watched in a while… The people watching this video are probably not stupid, so don't treat us like it!
Also, speak properly, you're not a 'gangsta' and it doesn't make science cool.
Taking time out of chemistry alevel to watch this….
LSD
I don't know actually.Some people just get offended easily..
