Question of the Past

I just remembered a question I had thought up a long time ago to ask my old Science Teacher but never did. Maybe you guys can answer me.

"If I took one of the most acidic substances Hydrochloric Acid and combined it with one of the most basic Sodium Hydroxide, would I be able to safely ingest the result? HCl+NaOH->NaCl+H2O seems to say "yes" the end result would be harmless salt water, but is this formula correct?

Assuming you get the stoichiometry exactly correct, then yes.

I don't know about the phenophthalein, however.
