How do you write out an equation where HCl is added to NaOH?

Question: How do you write out an equation for the strong acid-strong base titration where HCl is added to NaOH? My other question is it says NaOH is added to HCOOH; what does this equation look like for this strong base-weak acid titration? The book has HCOO- + H2O ---> HCOOH + OH-. Why is it not NaOH + HCOOH ---> NaHCOO + H2O?

Answer: Remember acid + base = salt + water. The acid and base will dissociate: H+ + Cl- + Na+ + OH- ----> Na+ + Cl- + H2O. Ans2: If its a titration then again write salt + water. Also strong base and weak acid gives alkaline soln. At stoichiometric pt soln is basic (salt + water), then look to see if salt is acidic or basic and write the following equ:NaHCOO + H2O ------> HCOOH + OH- + Na+. NaOH is an extrememly strong base and will almost always disassociate is solution. Na+ is a spectator ion and is usually not included in overall titration equations.
