sodium chlorideHow can we make sodium chloride? The first part of the name is 'sodium', so we need a base containing sodium. We could use sodium hydroxide or sodium hydrogen carbonate, for example. The second part of the name is 'chloride', so we need to use hydrochloric acid.Here are word equations for those reactions.sodium hydroxide + hydrochloric acid → sodium chloride + watersodium hydrogen carbonate + hydrochloric acid → sodium chloride + water + carbon dioxideIt would be very difficult to neutralise the acid in these reactions perfectly exactly. Some acid or base would be left over. So it would not be safe to taste the sodium chloride solution produced.
