10X Maleic Acid Buffer - (Oct/28/2008 )


I wanted to prepare 10X Maleic Acid Buffer (traditional recipe: 116g Maleic Acid, 88g NaCl - adjust to 1L and adjust pH to 7,5 with solid NaOH).
But I only have Maleic Acid Disodium salt... Can I use it? Maybe like this:
160g Maleic Acid Disodium (1 mol)
88g NaCl and then just pH eitheir way

Can someone help me?
Thanks, Diana


yes, but, be aware that you may increase the salt content of your medium (probably not enough to make a significant difference in your application).
