Question

PLEASE HELP, GIVING MEDAL
Explain, in a step by step procedure, how you would use titration to determine the concentration of a calcium hydroxide (Ca(OH)2) solution.

Answer 1

Calcium hydroxide is a strong base. So you will need to use a strong base to titrate.

Answer 2

First, measure out the volume of your calcium hydroxide solution.

Answer 3

Then, fill a burette with a known concentration of a strong acid (make sure you note the initial volume of the acid.

Answer 4

You will need either an indicator that changes color at a pH of 7 or a pH meter to determine when the calcium hydroxide has been neutralized.

Answer 5

Add the acid into the base slowly and stop exactly when the pH is 7. Note how much volume has been used of the acid to neutralize.

Answer 6

Concentration*volume =moles of acid. Make sure the units of volume are consistent to cancel.

Answer 7

Use the balanced neutralization reaction to determine the mole ratio and calculate the number of moles of calcium hydroxide.

Answer 8

Moles of calcium hydroxide/volume of calcium hydroxide is the concentration.

Answer 9

Make sense?
