Charge balancing ??
« on: January 06, 2015, 03:35:10 PM »
My teacher told me a concept of charge balancing. i was just listening to him by mistake i forgot to write down the concept.So  now my notebook is seeming unknown to me . Can anybody help in understanding this concept ??
now i have just one example and some examples which are incorrect i am just writing the correct example -

[H+]  = [OH-] + [HSO4-] + 2[SO42-]

I just wrote down it comes from charge conservation .
positive = Negative
No. of H+ = No. of OH- + No. of HSO4- + 2(No. of SO42-)

so now please help me out  ???
why we multiplied the [SO42-]  by 2 ??

Because it has two negative charges. The number of negative charges contributed by the SO42- ions is twice the number of these ions.

Solutions are (almost) never charged - they are electrically neutral. That means amount of positive charges must equal amount of negative charges.

Why is sodium hydroxide NaOH but sodium sulfate is Na2SO4?

No need to be sorry, dumb mistakes are part of the learning curve.

And they don't end the day you graduate.
