Sodium Thiosulfate LR 0.2M 1L Standardise before titration
50022-1L

Product information

0.2M = 49.6g/L = 4.96%

Use for qualitative testing - not for use in titrations , unless standardised prior to use

CAS 7772-98-7

Formula Na2S2O3.5H2O

Mwt = 248.18

Non Hazardous

One molecule of thiosulfate ion loses or donates one electron  in an oxidation/reduction  reaction

Therefore, Normality = Molarity (e.g., 0.1 M = 0.1 N)

1N = 1M ; 

N/5 = 0.2N = 0.2M

N/10 = 0.1N = 0.1M

N/20 = 0.05N = 0.05M

Do not confuse with all Molar solutions as valency determines Normality ie  Here Thiosulfate has a valency of 1 in a redox reaction as1 molecule donates 1 electron
