Chemistry Lesson: Ph Tests for Acids & Bases : Chemistry Lesson: How to Make a Ph Indicator

[gulfland]

DEAR VIEWERS,

FOR ASTONISHING FACTS, JUST TYPE ON THE SEARCHING BOX:

Quran and Science

SEVEN PARTS! YOU MUST LIKE THEM!

While Im here for a chemistry clas presentation

*sighs*

[pinkbatas]

are we making soup?

[TheHorribleGuitarist]

im here cus of a school project

*sigh*

Also it is pH not Ph or PH. The letters stand for potential of Hydrogen so it is important to always use an uppercase H for Hydrogen.

If you are concerned about kids try breaking the cabbage apart with your hands and soaking it overnight in water, and your results will be:

No giant containers of scalding, boiiing water, No large, sharp knifes,

just cabbage juice

and best of all...

no lawsuits :-)

[lizistar9673]

can you use this process for other indicators too? (exp: poinsettia, beet)

[Dragonboy476]

Nice Job posting the transcript OVER the video.......

[melvyn3000]

It's actually pH.

[i5Alex]

@melvyn3000 True, anyways i have a Chemistry exam in 15 minutes and i dont know shit :/ evn tho i like experiments and the whole thing i just cant memorize all those chemical thing's whatever they ar called... fusions? anyways all i know is H2O O2 N2O and Cu LOL :/

[magnusalexa]

does anyone know if petroleum spirit (lighter fluid) after evaporation leaves any harmful residue?

[bhabooshka]

she's a milf

[mecthing3]

2 minutes to cut up cabbage. put water in it and then throw it away. what a waste

[magnusalexa]

@mecthing3 not a waste at all, a red cabbage costs a lot less than PH test kits

[2ndviolin]

Eat the cabbage! (What a waste).

[LucentTwinkle]

i think she meant fourths; not 'fours' as people are stating

[killerkitty777]

its called 'quarters' not 'fours' lol

[soulxofxgirl]

dammit i just wanna know the properties of acids and bases, come on i have a final 2morrow snif snif

[SoldoutGodchaser]

try the chemguy or vu chemistry. this is not info to pass a final

[phj1990]

I thought this was a test for Ph(enyl) groups in organic molecules.

I think you meant this is a pH test.

[RailoX]

She took two minutes to say: Cut the cabbage into fours, boil it, take out the water and there's your indicator.

[509g1]

shes thick

[DumBlondie101]

is this all their is cuse i dont have red cabbage

[adejareojo]

chemystery indeed

[andrewx7441]

lol beethoven

[RockManAU]

Can I suggest you tell us what color the cabbage turns for both acid & alkaline substances - then the vid may be useful.

Thanks.

[beethovenbix]

...'Sorry'- ...'than the average person'.

[beethovenbix]

"She Says...'After you boil it...You kinda discard the cabbage cos' you cant use it again'.???????????????????????­????? Isn't she aware that - after you boil it...you can actually make very good use of the cabbage by

EATING IT instead of wasting it !!!! I thought Science Teachers were meant to have more common sense that the average person"????

kool? ur sad

[aardvarkpwnage909]

kool =)
