Acid Base Strength

What determines the degree to which an acid or base is weak or strong?

• how well the solute is ground up

• how high the temperature of the solvent is

• how well it dissociates or ionizes in water

• the pressure it's mixed under

How is pH related to the concentration of hydronium ions in solution?

• high concentration is a low pH

• low concentration is a high pH

• neither answer offered is correct

• both answers are correct

Are strong acids and bases good electrolytes?

• yes

• no

• depends on the acid or the base in solution

• acids and bases don't have anything to do with electrolytes

Why is pure water neutral?

• it contains an equal concentration of hydronium and hydroxide ions

• it has an even number of hydronium ions

• it has an even number of hydroxide ions

• it doesn't contain any hydronium or hydroxide ions
