1. Preparing Solutions

2. Preparing Solutions
Standard Solution: A solution in which the precise concentration in known
There are two methods for preparing standard solutions
From a solid
By dilution

4. Preparing Solutions from a Solid
In a beaker, weigh the amount of solute required
In the beaker, dissolve the solute in distilled water
Use a funnel to pour the solution into a volumetric flask
Inverse to mix.
Dilute to the mark with distilled water
