Chem Ch 8 = preparing standard solution by diluting a concentrated solution

step 1

calculate V1 = concentrated reagent required

step 2

add distilled water to volumetric flask (half the base)

step 4

transfer stock solution from pipet to volumetric flask

step 5

add distilled water using a wash bottle then a medicine dropped until bottom of the meniscus touches the graduated line

step 6

put stopper, inverting technique

Air valve

A in pipet bulb

Suction

S in pipet bulb

Empty valve

E in pipet bulb
