Sulfuric Acid Concentration Chart
Sulfuric Acid Concentration Chart
(OP)
Hello All,
I am trying to locate a chart for looking up sulfuric acid concentration. We have 96% to 98% Sulfuric. I want to take a sample, measure the specific gravity and temperature. Then take this data and with the chart I can find out what strength my Sulfuric is.
All help will be appreciated.
Thank You,
Ken

RE: Sulfuric Acid Concentration Chart
My 6th Edition of Perry's Chemical Engineers' Handbook has a table of sulfuric acid densities versus wt% concentration ranging from 1% to 100% (in increments of 1%) for temperatures ranging from 0 deg C to 100 deg C (in increments of 10 deg C).
I am guessing that later editions probably have the same table.

Kindly note that between 0 and 60 Celsius, there is an anomaly attributed to hydrogen bonding, by which 97% acid has a maximum density. Therefore, two solutions, one above and one below 97% may show the same densities.

I imagine that if you have a way to dilute a measured sample of the concentrated acid, with a measured quantity of water, and then take the density of this mix, by the use of tables as those mentioned by mbeychok you'd be able to determine the concentration of the original sample.
RE: Sulfuric Acid Concentration Chart
The specific gravity profile of sulfuric acid flattens out just before that maximum point so other properties (e.g. refractive index, sonic velocity) are usually used in this concentration range. If you intend to mix acid and water samples, please use caution - it is a very exothermic (read that as energetic) reaction.

My old employer use to have a chart. The operator would measure the density and temperature and look up the concentration.

From its data can be created concentration-density excel chart, although there are covered a lot of values
