If no chemical reaction is taking place then you simply have a soluton (solute + solvent). Depending on the context, either of these situations could suffice.Annie Ransomhttps://www.blogger.com/profile/13561862234261053360noreply@blogger.comtag:blogger.com,1999:blog-973980610382848719.post-43485256640617731712009-03-22T21:17:00.000-07:002009-03-22T21:17:00.000-07:00Can we determine change in viscosity under the eff...Can we determine change in viscosity under the effects of temperature changes by utilizing Stokes law? like would that fit with this lab or is it going into something off topic?brian [thebaker]https://www.blogger.com/profile/16932684783620218700noreply@blogger.comtag:blogger.com,1999:blog-973980610382848719.post-37219880256709750002009-03-22T21:04:00.000-07:002009-03-22T21:04:00.000-07:00just throwin it out there...just throwin it out there...dustinhttps://www.blogger.com/profile/02075234186252745868noreply@blogger.comtag:blogger.com,1999:blog-973980610382848719.post-63677158240712357852009-03-22T19:30:00.000-07:002009-03-22T19:30:00.000-07:00alright so 4 the viscosity lab is adding a chemica...alright so 4 the viscosity lab is adding a chemical to the initial liquid considered making it a different liquid and therefore not a valid comparison?dustinhttps://www.blogger.com/profile/02075234186252745868noreply@blogger.comtag:blogger.com,1999:blog-973980610382848719.post-64042456924038269872009-03-12T22:44:00.000-07:002009-03-12T22:44:00.000-07:00And can that heating take place over roughly 10 ho...And can that heating take place over roughly 10 hours per sample?
