Hydroiodic acid, Potassium hydroxide, Carbonic acid, Ammonium hydroxide, Potassium iodide, Butanol, and sucrose. Neutralizing acid spills with strong bases, such as sodium hydroxide or potassium hydroxide, can cause a violent exothermic reaction, and the base itself can cause just as much damage as the original acid spill. So they are both highly exothermic. Sodium Hydroxide (NaOH) is white and odorless solid.
