Red Cabbage pH Indicator

[JesusLovesus118]

Hmmm. Hmmm Hmmm Hmmmm what can I say it is very good for you to learn off I you didn't know about this system whatsoever I know it's not about the camra but It wasn't that clear at all. I esspcailly like when she/he really expermented with Iye. I don't know if you saw the coulor (I did! ) but it was really cool.

It was just the Camra that le me down

typo 'i know* you

[cuteglamourama]

Any alternative for the Red Cabbage? I can't see any red cabbage here in the Philippines. And I really need to do that chemistry magic, it's our project.

[TheCentralServices]

Without cabbage there would be no science!

[X0Meghan454]

lol fynny

[KbHonora734]

me like

[batratrisha]

the ph of lemon juice is 1....according to by science book...so shouldn't lemon juice be stronger then vinegar????

[zeinizim]

@batratrisha not all lemons are the same while vinegar is much more regulated

3:55 i shat my pants !!!!!

[cruzcontrolzzz]

what are the dependent and independent variables im having truble with this!!! sorry no need to shout..

[MILeyBERs]

is this easy to make?

[SuperMalik1234567890]

Will it Blend? That is the Question. :P

[fazalabh]

I tried with my daughter mixing SAFFRON POWDER. Came out a RUSTY BROWN Colour like Zircon Gem, which is kind of nice.

[coolgirl101ful]

you could have used a blender

[bkcutie22]

Im doing this for my Science Fair Project!!!!

[PureTeenageIgnorance]

Damn,all I got is green cabbage.

[iloeshoesgab]

whats the thesis of this project

[Momnamednancy]

why were you shaking the cabbage at the beginning? why couldnt you have just boiled it down?

[lilybabe95]

lol I love how you talk.. you talk like a really cool scientist haha :) and this is a great experiment it's fun and safe :)

[johntheawsomeful]

Thank you

[nollidXrocker]

Say i only wanted to test 1/2 and inch of water.How much red cabbage juice would i need for that?

[shasgurl]

it doesn't surprise me that the lye gave such a result. many public water departments use lye to neutralize and balance the ph of public water supplies. i'm guessing you didn't know that...

[poalar234]

dudewhich part of it looks like a red ???

[rhkj101]

i always thought it was purple cabbage

[JesusLovesus118]

@rhkj101 lol

[TheUFOclan]

i did this for my 6th grade Since Fare and went to County. XD

[stupithose]

were did u get the numberz 2 4 7 9 13

[cjstk3516]

thx

[unknownuser109]

wtf is this

[beansterman1998]

they did this in my school

[chillingonthefence]

Did that back at skool. Awsome. If only science research was that much fun.

[denelson83]

Should have tried hydrochloric acid. It might have given you a sort of orange colour.

[nhojmabon]

Nice demonstration :)

[Superwassaman1712]

is this a good science expiriment project?

[dbc616]

yeah it'd be great

[LifezMysteries]

@dbc616 Great vid, great description and visual details

:) thumbs up

[hongkong743]

lemon jiuce ph = 2.3

vinegar = 2.9

u r wrong idiots

[dbc616]

And finding the "exact" pH is completely useless and irrelevant.

[z4294967296]

Well he might be saying that Lemon juice has a lower pH than Vinegar. In the video you have it reversed.

Is your red cabbage juice pH neutral? The pH in tap water varies considerably. I know this is a relative test. But when you apply numbers, you may mislead the audience in thinking you're specifying some sort of precision.

Very cool video anyway!

[dbc616]

You may not know this, but those little curved lines before "pH" mean "approximate."

[z4294967296]

LOL... So Lemon juice is approximately more basic than vinegar?

Obviously you're not implying that. Nor do I want to get into a semantic argument. What I meant was that you shouldn't be so sensitive with criticism.

hongkong743's was very harsh -- He misinterpreted your video. Instead fighting fire with fire...Maybe agree, take note, and try to be more clear in the future videos??

[chillingonthefence]

@dbc616 Haha

[jailyknoppert]

@dbc616 but you make it sound like vinegar has a lower pH than lemon juice. The point wasn't about exactness, but rather your demonstration is incorrect.

[culaflex]

@hongkong743 u dnt have 2 be mean n smart nme calling kindergarden

[Davincifan98]

Nice narration on there, David. :) Awesome colors at the end!

[dbc616]

Thanks

[TheAmateurChemist]

Good! I would have used an organic solvent like an alcohol to extract the cabbage flavanoids because it will keep much longer than if water is used as the solvent.

[dbc616]

Yeah I considered a different solvent, but I also considered that this is supposed to be a home experiment. However, I'm planning to elaborate on this video by possibly doing that, and I might make pH test strips.
