Sodium Silicate Concentration
« on: June 15, 2016, 04:07:54 PM »
Hello dear chemists;

For my IB Chemistry HL Internal Assessment I am planning to measure the silicate contents of various silica-cat-litters from different brands. I will first synthesize sodium silicate from the silica gels by the addition of NaOH. But after that I do not know how to measure the concentration of sodium silicate in these solutions. Any methods?

Thank you!

Whether you use an ICP-MS or a wet chemistry test, you will have to dissolve the silicate in HF.  Not a task for a novice, and I'm sure the school won't let you.  You should quickly select something else to work with.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Do you have any idea of the other kitty litter ingredients?

If there are all organic, you might be able to do a gravimetric analysis
by ashing the sample at high temperature (500C).

Good luck
