You guys are my last resort

Can somebody explain and show me how to calculate titration stuff for GCSE (im 15)

Here is an example

Zac uses 25.0cm^3 of hydrochloric acid of concentration 3.65g/dm^3 to neutralize 25cm^3 of sodium hydroxide solution. What is the concentration of the sodium hydroxide solution

HCL+NaOH--->NaCl+H2O

lemme see if i can do it now that i found a way

HCL(1) NaOH(2)
RFM 36.5 40
vol 0.025 0.025
conc 3.65 4
m 0.09125 0.1

conc is 4

yay i got it right

thats ballancing equations..

im 13 and we learn it in 8th grade :P
you got to add a coefficient to balance the equation that makes up the new substance..

PortableZ · May 2010

oh wait, nvm..
my badd..
we dont learn to find the concentration yet :P

NaughtyBella · May 2010

No wonder i dropped out of Honors Chem second semester. Stuff is confusing

:P

-___- i can find out concentration easily. Formulae is C=M/V
Just they dont give you M so you have to find M using the know mass of the other solution. It's called titration btw.

And bella, not surprised, you fail at most things:O

NaughtyBella · May 2010

Bahahaha.
Can You do calculus haze?
I didn't fail at that

I was smart in school :P
CF has nothing to do with this xD

EmperorLulu · May 2010

What is this calculas you speak of o.O probably got a different name here.

NaughtyBella · May 2010

I don't know what it's called in different places. O.O
It's for smart math people lets just say that ;D

EmperorLulu · May 2010

Oh i do that. I got 26% in the practive of it o.O

Chemistry help please
