convert oxalic acid 2N to 1N

dear all
I am working in powder coating plant last few years are in Qatar.in Qatar there have difficulty to get proper chemical in local market. but now days For the testing of chrome free conversation layer I require oxalic acid 1N as per the chemical supplier specification requirement for the analyzing. but unfortunately in the market only available oxalic acid 2N.now I want to convert oxalic acid 2N to 1N.so if any one knows about this please help me.

RE: convert oxalic acid 2N to 1N

Oxalic acid is a diprotic acid, which when fully dissociated in water, splits out as follows

H2C2O4 -> 2 H30+ + C2O4=

H3O+ = hydronium ion
C2O4= = oxalate ion

normality of a n-protic acid is is = (no of moles / litre) x n

So what you have now is a solution with 1 gm mole of oxalic acid / litre of solution.

To dilute it to a 1N solution, add one litre to each litre of the solution you have now ( or 500ml acid to 500ml water)

When mixing, add the acid slowly into the water, and not the other way round, and stir well while adding - use distilled water. Use glass beaker / stirrer and wear gloves/ safety specs
