Hi!

Who could give me the correct value of NaCl's viscosity (in solution)?

Thanks!

Regards,

Look in your library for either of the following :

Handbook of electrolyte solutions. V.M.M. Lobo. Elsevier, 1989. 2 vols.

Handbook of electrochemical constants. R. Parsons. Butterworths Scientific, 1960.

In general, the viscosity is a function of temperature and concentration.

I'm leaving this open. Tyutyu, do not post multiple copies of the same post - it is considered spam.

Wouldn't it depend on the concentration and temperature of the solution?

Yes of course...in "standard" conditions it would be ok for me.

Temperature: 298F (or 25 C)
Concetration: 0.1 mol/L

Thanks

Sorry, I don't know myself. I don't know much about chemistry.

Ok Daminc lol!

Does somebody know the value that I am searching? It is applied to process numerical simulation so I nedd a correct value and not an approximation.

The problem is that I don't have the possibility to check in the books mentionned by Gokul....

Thanks.

For whatever it's worth : at a concentration of 0.1M, the mole fraction is 0.1/55 or less than 0.2%. I do not expect the viscosity to be off by more than 0.5% from that of distilled water at NTP. Do you need a better accuracy than that, really ?
