Sodium bicarbonate and Acid Neutralization time

In summary, when baking soda is used to neutralize acid, it forms a double displacement reaction with hydrochloric acid. This reaction creates bubbles, but if too much baking soda is added at once, the mixture can overflow. However, as more baking soda is added, the reaction reaches a neutral state and the bubbles stop forming. The reaction is almost instant, with the main factor being the speed of mixing. This method can be used to prevent skin damage in case of accidental acid spills and can be found in most First Aid kits.

If let's say a person accidentally has acid spilled in his hands, if he sprays or reaches for baking soda (or sodium bicarbonate) to neutralize the acd, how fast is the reaction? is it enough to avoid any skin damage? Are these part of any First Aid kit? Just curious about this.

I read:

"The reaction between baking soda, also known as sodium bicarbonate, and hydrochloric acid is a double displacement reaction. The reactants combine to form sodium chloride, water and carbon dioxide. The carbon dioxide forms bubbles that cause the mixture to overflow a flask if too much baking soda is added at once. Eventually, as more baking soda mixes with the acid, the bubbles stop forming as the acid reaches the neutral state and is no longer able to provide the hydrogen molecules needed to break down the sodium bicarbonate."

You can think of the neutralization reaction as if it was instant - no reaction really is, but when they take microseconds they for most practical purposes can be treated this way.

The limiting factor here is the mixing speed, not the reaction itself.
