10.00 mL of HCl is titrated to a neutral endpoint with 35.78 mL of 0.200M NaOH. What is the molarity and normality of the HCl?
The definition of molarity (abbreviated as M) is moles/liter (or mol/L).
HCl and NaOH are a strong acid and strong base, respectively, and therefore both dissociate completely. HCl dissociates in the solution to give 1 mol of H+ and 1 mol Cl- per mole of HCl, and NaOH dissociates in solution to give 1mol of Na+ and 1 mol OH- per mole of ...
At the neutral endpoint, the number of moles of HCl must also be the same as the number of moles of HCl due to the equal molar relationship discussed in the solution. Calculations and answer are included.
