You've accidentally spilled some acid on the floor of your home. What are some expected observations you should be able to make regarding this spill (qualitative observations)? What things would you expect to observe from the acidic spill that you may not observe if it was an alkaline substance that spilled? What is a substance that you can use to neutralize the acid spill? Why is this substance a good neutralizer? (justify your response using appropriate scientific vocabulary and reasoning).

Some $\color{gold}{qualitative!~ observations}$ might be: 
- A sharp, pungent smell
- Color change, such as blue litmus paper turning red when tested
- Some heat may be released and/or bubbling/fizzing if the acid is reacting with certain substances.

In $\color{green}{Alkaline~ Spills}$, the differences would be 
- A red litmus paper would turn blue.
- A less intense odor. 
- Saponification with proteins and/or slippery/soapy feel.

One substance that is normally used to neutralize acidic solutions/spills is $\large\color{red}{baking~soda}$, aka sodium bicarbonate.

Baking soda is a weak base that can safely neutralize acids. It produces water, carbon dioxide, and salts when it reacts. So it is non-toxic.
