Properties of Acids and Alkalis 🧪
### Definitions:
* **Acid (Arrhenius)**: Substance which in aqueous solution produces hydrogen ions ($H_3O^+ / H^+$) as the only positive ion.
* Turn blue litmus paper red. Sour taste. $pH < 7$.
* *Strong Acids*: $\text{HCl}, \text{H}_2\text{SO}_4, \text{HNO}_3$ (completely ionize).
* **Base (Alkalis)**: Substance which produces hydroxide ions ($\text{OH}^-$) in water.
* Turn red litmus paper blue. Bitter taste and soapy feel. $pH > 7$.
* *Examples*: $\text{NaOH}, \text{KOH}, \text{Ca(OH)}_2$.
Core Takeaway: Acids produce H+ and turn litmus red; bases produce OH- and turn litmus blue.
