Why can you use salt water to wash vegetables before cooking ;D

To get rid of dirt on the vegetables. Also vegetables may have been handled alot before you bought them so it is common practice to wash vegetables before using them. Especially salad leaves, which can be washed then spun dry in a salad spinner before tossing and dressing.
There is no science without fancy, and no art without facts.

Yeah, but I think you should tell more details, about the way how it does, because this is not only belonged to chemistry but also physics( I think so;D)

First, no offense, but I'm starting to notice you topics/posts aren't very coherent. Your jumping around in questions and ideas. This can make it difficult to help you.

In the lab, do you think Al will react with CuSO4 ? Why, ;D

Look at a reactivity series table. Is Al higher than Cu?

vhpk, your posts have a tendence to regard this forum as a quiz; I am not here to prove I can do these things; I have more things to do with my time.

If you need help be specific on what you dont understand and show any attempts at solutions. Then I am more than willing to try and help you - not just to solve questions, but to get you to understand how to do something and why.

In regards to DevaDevil's comment...

A lot of the regulars here are undergrads, graduate students, or already have a degree of some type in a field of chemistry. That means that they know or are learning advanced topics in chemistry.

Oops. I forgot to add the part that most people have already long learnt the topics involved with the question(s) which makes it redundant for them to spend time being requized. I've been so tired lately, and lapsing in thought. Either way DevaDevil, your comment spurred my comment.

Oh,no, I've joined some chemical forum in my country, I think that all of you understand the problem wrongly. I recognized that I made some problem, but not to prove me good, I want to involve to the reality, I only want to share my knowledge and experience to another. I don't have any degrees because I'm only 15. I didn't made quiz, please understand for my effort. :-[
