Re: Solutions
Your solutions chart is fantastic and will help lots of us immensly. Whilst working thru it have noticed a small omission in Sodium Hydroxide. The 0.1M enrty doesn't specify an amount of water ,(ie 1 litre ) also same for first 2M entry. Could confuse the newer users.

Re: Solutions
Amanda, this is what I was going to send you, just download and have a look at these. Hope they answer your questions.
Re: Solutions
I use the attached table - covered in contact paper and stuck to the bench beside my scales in the Prep Room. The table is printed on bright yellow paper, but any colour is easier than white in the Prep Room. These are the most common chemicals/molarity which we use.

Re: Solutions
Now this might sound stupid(and it really is) but I never new that you added acid to some solutions. Why is this?

Re: Solutions
Some of the solutions need to hold on to their solids. By adding a acid, it some times clears this, or clears the solutions, or can give it a longer shelf life.
