Chemistry and Mathematics!

[SMRJ]

Well first of all i am having an issue with the indicators used in titration in Chemistry ATP! Please give me some help with this!
And secondly i want help in maths in the topic of sets, i find difficulty in figuring out the least and greatest value! And i need some tips for transformations! Thank you! :? !

Posts some specific questions. I'll explain it. Telling generally won't clear the doubt anyways. (with year)

For maths, M/J 2004 Q#5c, 7!
Well i also remembered having a problem with mensuration, so I've added a question with that.

ya like zohaib said, can you be more specific...

 

[SMRJ]

@[MJ]: I've told the question numbers! What else do you want!?

For chemistry i can only say that the colors of all the indicators except for phenolphthalein is red in acids.
And for alkalis Blue for litmus
Orange/yellow methyl orange
Pink for phenolphthalein
no need for others.

Use this video and its remaining parts for a complete revision of O level sets according to the syllabus. I made this lecture some time back on someone else's demand. The rest of the parts can be found on this channel. http://www.youtube.com/user/alfredr8

I'll post A level lectures in this summer. So, you can save this link with you.
