How would the calculated concentration of the HCI be affected, if the sodium hydroxide were poured from a beaker that contained some water before that NaOH were added to it ?

Hmmmm. Wondering if the NaOH were solid, or in a solution?
hmmm. adding water dilutes the HCl
adding NaOH neutralizes the HCl
so, what do you think?
Seems like an MCAT question. You would over estimate the concentration of the acid.
