What is the pH level at the endpoint?

7

AS the concentration of a weak acid increases, conductivity (increases, decreases, remains constant).

increases

As concentration of a weak base increases, the pH (increases, decreases, stays the same).

increases

As the concentration of a weak acid increases, the number of ions (increases, decreases, remains constant).

increases

As the strength of a weak acid increases, the conductivity (increases, decreases).

increases

As the strength of a weak acid increases, the proportion of ion to molecules (increases, decreases).

increases

At the same concentration a strong acid will have a (higher, lower, the same) pH as a weak acid.

lower

What do strong bases dissociate into?

metal ions and hydroxide ions

Weak acids (fully, partially) ionize in aqueous solutions.

partially

Strong and weak refer to...

particles that ionize to form ions in acids or bases

A strong acid is (very concentrated/ primarily exists) as ions.

primarily exists

What are the products of neutralization reactions?

salt and water

A strong base is a (non electrolyte/ weak electrolyte/ strong electrolyte).

strong electrolyte

How is the strength of an acid determined?

the degree the acid will react with water to form ions

What makes strong acids have higher amounts of hydronium ions?

the fact that they dissociate fully

How do you know when a titration has reached its endpoint?

the indicator will change colors

How do the number of OH- ions compare to the H3O+ ions?

they are equal

What makes weak acids have lower amounts of hydronium ions?

they do not fully ionize and dissociate

A weak base is a (non electrolyte/ weak electrolyte/ strong electrolyte).

weak electrolyte

What is a titration?

a process used to determine the unknown concentration of an acid or base

What is a standardized solution?

a solution which the concentration is known

What are the reactants in neutralization reactions?

acid and base

Why does a weak acid have a higher pH level than a strong acid with the same concentration?

because strong acids completely dissociate causing the pH to be lower. weak acids only partially dissociate.

As concentration of a weak acid increases, the pH (increases, decreases, stays the same).

decreases

Strong acids (fully, partially) ionize in aqueous solutions.

fully

Concentrated and diluted refer to...

how much acid or base is dissolved in a solution, the moles

What is produced when acids react with water?

hydronium ions; H3O+

What do weak bases dissociate into?

hydroxide ions and the acid conjugate of the base

What is produced when bases react with water?

hydroxide ions, OH-
