Hi Lada,
It is the easiest way and most accurate way I have found to do the pH range - and it works.

Hi there, :-) here is the way to make your pH range hope this is of some use Making PH Solutions To Make 200ml of each solution To make a 200ml solution of PH1 to PH7 PH1 = .1 mol HCL 220ml (Base Solution) PH2 = 20 ml .1 mol HCL + 180ml distilled Water = 200ml = PH2 PH3 = 20 ml PH2 Solution + 180ml ...

I am currently cleaning up my test tubes, I also use 3m HCl and leave them overnight. This solutions works for several applications, just pour it our into a beaker and then refill your next load of test tubes.

Good luck

I use Volumetric flasks and to extract the 20ml from the previous pH I use a 20ml Pipette then transfer it to the volumetric flask.
Good luck

Here is a copy of how we do our ph hope this helps Making PH Solutions To Make 200ml of each solution To make a 200ml solution of PH1 to PH7 PH1 = .1 mol HCL 220ml (Base Solution) PH2 = 20 ml .1 mol HCL + 180ml distilled Water = 200ml PH2 PH3 = 20 ml PH2 Solution + 180ml distilled Water =200ml PH3 P...

The Recipe that we use is
Sand
Copper sulphate
marble chips
Plaster of Paris

This works great for us.

A tip is when almost set make an indent into the size squares that youwant and this makes for much easier breaking when it has set.

Good Luck
