Potassium Silicate Test
Procedure
1. Using a graduated cylinder or pipette (+/- 1 ml, accuracy is not critical) add 20 ml of water to a small flask or beaker (50 to 100 ml flask is recommended).
2. Add 2 or 3 drops of Methyl Red indicator solution.
3. Add 0.2 Normal HCl until the solution turns red. It should take only one drop.
4. Using a suitable syringe (1 ml syringe recommended for better accuracy) add 2 ml of filtrate to the flask and swirl to mix. The solution will be yellow to yellow-brown.
5. Titrate the solution with 0.2 Normal HCl to a pink-red (pH=5.4)endpoint. Swirl the flask between additions of HCl. Watch where the drop of HCl hits the surface of the solution. If the drop turns red and is distinguishable from the surrounding liquid, the endpoint has not been reached. If there is not a color change as the drop hits the surface, the endpoint has been reached. Record the volume of titrant used.
6. Add approximately 1 gram (1/4 teaspoon) of sodium fluoride to the flask. Swirl to dissolve(+/- 10 min). The solution should change from pink-red to yellow-brown.
7. Titrate with 0.2 Normal HCl to the red-pink (pH= 5.4) endpoint. Again, the endpoint is reached when no color change is observed as the drop hits the surface.
8. Record the second volume. It is used to calculate the percent silicate I the mud.
