What is the molarity of HCl found in a titration where 100 ml of HCl is titrated with 10 ml of 6 M NaOH?

Jeremiah Adams

#[HCl(aq)]=0.60*mol*L^-1#

We assess the reaction...

#HCl(aq) +NaOH(aq) rarr NaCl(aq) + H_2O(l)#...

#n_"NaOH"=10*mLxx10^-3*L*mL^-1xx6.0*mol*L^-1=0.060*mol#

Given the molar equivalence, thus a #0.060*mol# quantity was present in the #100*mL# volume of #HCl# titrant...

#[HCl(aq)]="moles of HCl"/"volume of solution"=(0.060*mol)/(100*mLxx10^-3*L*mL^-1)=0.60*mol*L^-1#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
