Can this reagent be saved?

Help please.  When mixing 0.5M EDTA pH 8.0 according to Maniatis,
I got too many NaOH pellets in there , so the pH is >9.  Can I
do something to fix it?

Also, does anyone know the shelf life of 1M MgCl2 solution?
Is it OK to use if it has been sitting around at room temperature
since March in a clear glass container?

Thanks in advance for any help.
