Solutions, Acids, & Bases

Acids & Bases

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

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

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

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

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

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

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

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