Calculate the concentration of a 50.0mL sample of HBr acid, which was titrated with 37.7 mL of 0.57 M NaOH base.
Why is an overshot endpoint not a good titration?
Write the equation.
HBr + NaOH ==> NaBr + HOH
mols NaOH = M x L = ??
mols HBr = mols NaOH (see the equation is 1!1 ratiio).
Mols HBr = M x L.
You have mols from above, you have L, calculate molarity.
