Can sodium hydroxide and hydrochloric acid kill you?

Answer 1

No. Sodium hydroxide and HCl will give sodium chloride (NaCl or common salt). Of course, either one on its own can kill you.

Answer 2

Both sodium hydroxide and hydrochloric acid are highly corrosive substances that can cause severe burns or tissue damage if in contact with the skin, eyes, or if ingested. Ingesting large amounts of these chemicals can be fatal, as they can cause damage to internal organs and disrupt bodily functions. It is crucial to handle these chemicals with extreme caution and seek medical attention immediately if exposed.
