Strong Acids and Weak Acids

• What do acids produce in water?

  Protons (Hydrogen ions)
• How do acids behave in aqueous solutions?


  They ionize and produce hydrogen ions
• What is a solution?


  A mixture formed when a solute dissolves in a solvent
• What does the concentration of a solution measure?


  How 'crowded' the solute particles are
• What does a higher concentration of solute indicate?


  More particles within the volume
• What characterizes a dilute solution?


  It contains a small amount of dissolved solute
• What characterizes a concentrated solution?


  It contains a large amount of dissolved solute
• What do acids in solutions provide?


  A source of hydrogen ions
• What happens when a strong acid is dissolved in a solution?


  It completely dissociates into ions
• Name three examples of strong acids.

  Nitric acid, Sulfuric acid, Hydrochloric acid
• How do weak acids behave in solution?


  They only partially dissociate
• What does the pH of a solution measure?


  The concentration of hydrogen ions
• What is the relationship between hydrogen ion concentration and pH?


  Higher concentration of hydrogen ions = lower pH
• What is the relationship between hydrogen ion concentration and pH?


  Lower concentration of hydrogen ions = higher pH
• What defines an acid in terms of hydrogen and hydroxide ions?


  It produces more hydrogen ions than hydroxide ions when dissolved in water
• What does the pH scale measure?


  The acidity or alkalinity of a solution
• What is dissociation in the context of acids?


  The breaking up of a molecule into ions when dissolved in water
• What does it mean when a substance is dissolved?


  It breaks up and is mixed completely with a solvent to make a solution
• What is concentration in a solution?


  A measure of the mass or amount of solute dissolved in a given volume of solvent or solution
• What is a solvent?


  The liquid in which the solute dissolves to form a solution
• What is a solute?


  The dissolved substance in a solution
• What is a proton?


  A positively charged particle
