I want to find out the physical properties of some additives with varying concentration with and without mixing in the water; also the best instrument to measurement of surface tension values with increasing temperature of same additives.
To get a helpful answer you need to tell us which properties you want to determine: viscosity? density?
Good ans simple instruments for finding the physical properties of varying concentrated additives in water are:
1. Simplest method is density measuring with a a) hydrometer or b) a Pyknometer >> https://en.wikipedia.org/wiki/Hydrometer
>>https://en.wikipedia.org/wiki/Pyknometer
Also refroctometer or viscosimeter can be used - depending of your specific question-
Johann HUMER: Thanks for the information sir.
Alan Parker:
Have any good instrument for Surface tension measurement, I now about stalagmometer but i found some error i.e. temperature of varying concentrated liquid not remain constant as it is open to atmosphere also made up of glass material.
