Titrations

Question 1

Strong acid base titration

Answer 1

Strong acid + strong base = salt and water
- titration is a way of determining the concentration of an unknown solution

Question 2

Endpoint

Answer 2

When the reaction has been neutralized, the colour of the solution will change
- the pH endpoint for all strong acid and base titrations is 7

Question 3

Equivalence point

Answer 3

When the moles of acid equals the moles of base for substances that have a 1:1 mole ratio (strong acid reacting with a strong base)
- refers to volume of titration needed to reach neutralization

Question 4

Titrant

Answer 4

• solution with known concentration
• goes in the buret

Question 5

Sample

Answer 5

• solution with unknown concentration
• goes in Erlenmeyer flask

Question 6

Indicators and titrations

Answer 6

• colour change of an indicator indicates when the reaction is complete- neutralized
• can be used to determine the Ph at the endpoint of a reaction.
