Acid - base titrations

Question 1

What is a titration?
-Hints - Volume

Answer 1

-technique used to ,measure the volume of one solution that reacts exactly with another solution.

Question 2

What titrations be used for?

Answer 2

-finding the conc of a solution
Identifying unknown chemicals

Question 3

What is a standard solution?

Answer 3

-solution of a known concentration.

Question 4

Step One of Acid Base titration

Answer 4

Add a measured volume of one solution to a conical flask using pipette.

Question 5

Step Two of Acid Base titration

Answer 5

Add the other solution to a burette, and record the initial burrete reading.

Question 6

Step three

Answer 6

Add a few drops of an indicator to the solution in the conical flask.

Question 7

Step four

Answer 7

Run the solution in the burette into the solution in the conical flask swirling the conical flask throughout to mix the two solutions till the indicator in the conical flask changes colour at the end point.

Question 8

Step Five

Answer 8

Record the final burette reading.

Question 9

What is a titre?

Answer 9

The volume of the solution added from the burette.
Initial reading - Final reading.

Question 10

Step six - Trail titration

Answer 10

Carry out a trial titration to find the approximate titre.

Question 11

Step seven- last one

Answer 11

Repeat titration more accurately by adding the solution dropwise as the end point is approached
-Repeat more titrations untill concordant results are obtained.
