I'm doing a titration lab tomorrow and I am not sure what the formulas are to calculate the moles of NaOH, the moles of HCl, and the molarity of HCl.
The objective of this laboratory is to determine the molarity of a hydrochloric acid solution using a known concentration of sodium hydroxide as the titrant.
volume of HCl in flask: 25.00 mL
the net ionic equation for the reaction is:
H+(aq) + OH-(aq) --> H2O(l)
I don't have the data now since I haven't done the lab yet but how should I set up to figure out the moles of NaOH, the moles of HCl, and the molarity of the HCl solution.

Standardization of NaOH: Acid Base Titration Objective: In this lab, you will accurately determine the concentration of a solution of sodium hydroxide (NaOH) using a 0.500M potassium hydrogen phthalate (KHP) standard solution. Background: Acid–Base Titrations When an acid reacts with a base, a neutralization reaction occurs. The H+ ions from the acid and the HO– ions from the base combine to form water and are therefore neutralized. The other product of reaction is a salt. For example, hydrochloric acid reacts...
