Does Sodium Hydroxide Kill Plants? | Hunker

A solution of sodium hydroxide is dangerous because of its high pH -- in other words, the high concentration of hydroxide ions. If the solution is brought to neutral pH by titrating it with acid, the hydroxide ions from the sodium hydroxide will be neutralized by hydrogen ions from the acid, and the solution will cease to be dangerous to plants.
