We have 2 methods, both work great. Depending on how busy you are to make
these up....

2.1 grams citric acid in 1 litre/liter of distilled water
pH to 6.0 with 1M NaOH
or 
Soln A : 10.5 grams citric acid in 500 ml distilled water
Soln B : 29.4 grams sodium citrate in 1 litre of distilled water
Mix 41 ml of A + 9 ml of B, make upto 500ml with distilled water, PH to 6.0
with 1M NaOH.

Have fun.
