NaOH Normality

Post by Stip » Wed Aug 03, 2011 7:26 am

Hi there,

Just wondering - If 50uL of 2N NaOH is added to 50uL of H20 what is the final normality of NaOH? I am struggling with my basics. please help

these are really basics. The amount is the same, volume is twice bigger -> concentration is twice smaller (half of original)

Cis or trans? That's what matters.

In general, c1v1=c2v2 where:
c1 = starting concentration
v1 = starting volume
c2 = ending concentration
v2 = ending volume

Jackbean already solved your particular problem, but you can use this equation to solve dilution problems in general.

If 50uL of 2N NaOH is added to 50uL of H20 what is the final normality of NaOH?

c1 = 2N
v1 = 50 uL
v2 = 100 uL
solve for c2
