1. Solutions, Acids, & Bases

2. Acids & Bases

3. Acids & Bases
Acids
substances that donate hydrogen ions to form hydronium ions (H3O1+) when dissolved in water

4. Acids & Bases Acids strong acids fully ionize in water
substances that donate hydrogen ions to form hydronium ions (H3O1+) when dissolved in water
strong acids fully ionize in water
weak acids do not fully ionize in water

5. Acids & Bases
Bases
substances that either contain hydroxide ions or react with water to form hydroxide ions

6. Acids & Bases Bases strong bases fully ionize in water
substances that either contain hydroxide ions or react with water to form hydroxide ions
strong bases fully ionize in water
weak bases do not fully ionize in water

7. Acids & Bases Acids & Bases degrees of acidity or basicity
measured by pH
concentration of hydronium ions in solution

8. Acids & Bases Acids & Bases degrees of acidity or basicity
measured by pH
concentration of hydronium ions in solution
pH < 7.0 → acidic
pH = 7.0 → neutral
pH > 7.0 → basic

10. Acids & Bases Acids & Bases at home… cleaning products are often basic
food products are often acidic

11. Acids & Bases Acids & Bases
mixing acids & bases may cause neutralization, forming water and a salt
Ex:
HCl(aq) + NaOH(aq)  NaCl(aq) + H2O
