Discussion Overview

The discussion centers around the viscosity of sodium chloride (NaCl) in solution, specifically seeking a precise value under defined conditions. Participants explore factors affecting viscosity, such as concentration and temperature, while addressing the need for accuracy in numerical simulations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • tyutyu requests the correct viscosity value of NaCl in solution, emphasizing the need for accuracy for numerical simulations.
  • Some participants suggest consulting specific reference books for viscosity values, noting that viscosity is dependent on temperature and concentration.
  • tyutyu specifies conditions of 25 °C and a concentration of 0.1 mol/L for the viscosity measurement.
  • One participant mentions that at a concentration of 0.1M, the mole fraction is low, suggesting that the viscosity may not differ significantly from that of distilled water at normal temperature and pressure (NTP).
  • tyutyu expresses frustration about not having access to the recommended books for verification.

Areas of Agreement / Disagreement

Participants acknowledge that viscosity is influenced by concentration and temperature, but there is no consensus on the exact value of NaCl's viscosity in solution. The discussion remains unresolved regarding the specific viscosity value sought by tyutyu.

Contextual Notes

The discussion highlights the importance of specific conditions (temperature and concentration) for viscosity measurements, but does not resolve the exact value or provide a definitive reference.

Viscosity of a solution of NACl

Hi!

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

Thanks!

Regards,

tyutyu

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 ?
