[(Molecular weight of k2cr207)/(No of elemental chromium*Molecular weight of elemental chromium)] * [Purity of salts(Assay%)/100]
[294.1846 /(2*51.9961)]*(98/100) = 2.772 gm in 1 litre gives 1000ppm of chromium.
is it correct?
kindly give any relevant literatures regarding weight of K2Cr2o7 taken
Parisa Ziarati
Dissolve 2.7476 (2.75) g K2Cr2O7 in water and make up the volume to 1 L. This solution contains 1 g Cr/L or 1000 mg mg/L.
