Some become obvious not to use. Also, extra decimal to the 100th's place is best with the pipet or mohr pipet but ones to the 10ths place can be done with the graduated cylinder.

Explanation / Answer

1) Transfering 8.15 ml of from one container to another = 10 ml Volumetric pipet

2) dissolving in about 20 ml of water to be titrated = 25 ml buret

3) Transfering 11.7 ml from one container to another container = 25 ml graduated cylinder

4)make 100 ml of diluted NaOH = 125 ml erlenmeyer flask
