How does titration affect molarity?
Titration affects molarity by changing the volume of the solution. For example, if you have a 1M solution of NaOH in 1 Liter, then you have 1M Na+ ions. If you titrate this with 1M HCl, then it will take 1 Liter of HCl to fully titrate this. However, your Na+ ion concentration is now 1 mole in 2 liters, or 0.5M. So titrations generally increase volume and reduce molarities
